Get the autoscaling capacity Added in 7.11.0

GET /_autoscaling/capacity

NOTE: This feature is designed for indirect use by Elasticsearch Service, Elastic Cloud Enterprise, and Elastic Cloud on Kubernetes. Direct use is not supported.

This API gets the current autoscaling capacity based on the configured autoscaling policy. It will return information to size the cluster appropriately to the current workload.

The required_capacity is calculated as the maximum of the required_capacity result of all individual deciders that are enabled for the policy.

The operator should verify that the current_nodes match the operator’s knowledge of the cluster to avoid making autoscaling decisions based on stale or incomplete information.

The response contains decider-specific information you can use to diagnose how and why autoscaling determined a certain capacity was required. This information is provided for diagnosis only. Do not use this information to make autoscaling decisions.

Get index template information Added in 5.2.0

GET /_cat/templates/{name}

Get information about the index templates in a cluster. You can use index templates to apply index settings and field mappings to new indices at creation. IMPORTANT: cat APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications. For application consumption, use the get index template API.

Path parameters

  • name string Required

    The name of the template to return. Accepts wildcard expressions. If omitted, all templates are returned.

Query parameters

  • local boolean

    If true, the request computes the list of selected nodes from the local cluster state. If false the list of selected nodes are computed from the cluster state of the master node. In both cases the coordinating node will send requests for further information to each selected node.

  • Period to wait for a connection to the master node.

Get term vector information

POST /{index}/_termvectors/{id}

Get information and statistics about terms in the fields of a particular document.

You can retrieve term vectors for documents stored in the index or for artificial documents passed in the body of the request. You can specify the fields you are interested in through the fields parameter or by adding the fields to the request body. For example:

GET /my-index-000001/_termvectors/1?fields=message

Fields can be specified using wildcards, similar to the multi match query.

Term vectors are real-time by default, not near real-time. This can be changed by setting realtime parameter to false.

You can request three types of values: term information, term statistics, and field statistics. By default, all term information and field statistics are returned for all fields but term statistics are excluded.

Term information

  • term frequency in the field (always returned)
  • term positions (positions: true)
  • start and end offsets (offsets: true)
  • term payloads (payloads: true), as base64 encoded bytes

If the requested information wasn't stored in the index, it will be computed on the fly if possible. Additionally, term vectors could be computed for documents not even existing in the index, but instead provided by the user.


Start and end offsets assume UTF-16 encoding is being used. If you want to use these offsets in order to get the original text that produced this token, you should make sure that the string you are taking a sub-string of is also encoded using UTF-16.

Behaviour

The term and field statistics are not accurate. Deleted documents are not taken into account. The information is only retrieved for the shard the requested document resides in. The term and field statistics are therefore only useful as relative measures whereas the absolute numbers have no meaning in this context. By default, when requesting term vectors of artificial documents, a shard to get the statistics from is randomly selected. Use routing only to hit a particular shard.

Path parameters

  • index string Required

    The name of the index that contains the document.

  • id string Required

    A unique identifier for the document.

Query parameters

  • fields string | array[string]

    A comma-separated list or wildcard expressions of fields to include in the statistics. It is used as the default list unless a specific field list is provided in the completion_fields or fielddata_fields parameters.

  • If true, the response includes:

    • The document count (how many documents contain this field).
    • The sum of document frequencies (the sum of document frequencies for all terms in this field).
    • The sum of total term frequencies (the sum of total term frequencies of each term in this field).
  • offsets boolean

    If true, the response includes term offsets.

  • payloads boolean

    If true, the response includes term payloads.

  • positions boolean

    If true, the response includes term positions.

  • The node or shard the operation should be performed on. It is random by default.

  • realtime boolean

    If true, the request is real-time as opposed to near-real-time.

  • routing string

    A custom value that is used to route operations to a specific shard.

  • If true, the response includes:

    • The total term frequency (how often a term occurs in all documents).
    • The document frequency (the number of documents containing the current term).

    By default these values are not returned since term statistics can have a serious performance impact.

  • version number

    If true, returns the document version as part of a hit.

  • The version type.

    Values are internal, external, external_gte, or force.

application/json

Body

  • doc object

    An artificial document (a document not present in the index) for which you want to retrieve term vectors.

  • filter object
    Hide filter attributes Show filter attributes object
    • Ignore words which occur in more than this many docs. Defaults to unbounded.

    • The maximum number of terms that must be returned per field.

    • Ignore words with more than this frequency in the source doc. It defaults to unbounded.

    • The maximum word length above which words will be ignored. Defaults to unbounded.

    • Ignore terms which do not occur in at least this many docs.

    • Ignore words with less than this frequency in the source doc.

    • The minimum word length below which words will be ignored.

  • Override the default per-field analyzer. This is useful in order to generate term vectors in any fashion, especially when using artificial documents. When providing an analyzer for a field that already stores term vectors, the term vectors will be regenerated.

Create or update a component template Added in 7.8.0

PUT /_component_template/{name}

Component templates are building blocks for constructing index templates that specify index mappings, settings, and aliases.

An index template can be composed of multiple component templates. To use a component template, specify it in an index template’s composed_of list. Component templates are only applied to new data streams and indices as part of a matching index template.

Settings and mappings specified directly in the index template or the create index request override any settings or mappings specified in a component template.

Component templates are only used during index creation. For data streams, this includes data stream creation and the creation of a stream’s backing indices. Changes to component templates do not affect existing indices, including a stream’s backing indices.

You can use C-style /* *\/ block comments in component templates. You can include comments anywhere in the request body except before the opening curly bracket.

Applying component templates

You cannot directly apply a component template to a data stream or index. To be applied, a component template must be included in an index template's composed_of list.

Path parameters

  • name string Required

    Name of the component template to create. Elasticsearch includes the following built-in component templates: logs-mappings; logs-settings; metrics-mappings; metrics-settings;synthetics-mapping; synthetics-settings. Elastic Agent uses these templates to configure backing indices for its data streams. If you use Elastic Agent and want to overwrite one of these templates, set the version for your replacement template higher than the current version. If you don’t use Elastic Agent and want to disable all built-in component and index templates, set stack.templates.enabled to false using the cluster update settings API.

Query parameters

  • create boolean

    If true, this request cannot replace or update existing component templates.

  • Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

          Indicates whether soft deletes are enabled on the index.

        • Hide retention_lease attribute Show retention_lease attribute object
          • period string Required

            A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

      • sort object
        Hide sort attributes Show sort attributes object
      • Values are true, false, or checksum.

      • codec string
      • routing_partition_size number | string

        Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

        Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

      • auto_expand_replicas string | null

        One of:
      • merge object
        Hide merge attribute Show merge attribute object
      • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

      • Hide lifecycle attributes Show lifecycle attributes object
        • name string
        • indexing_complete boolean | string

          Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

          Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

        • If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

        • Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

        • step object
          Hide step attribute Show step attribute object
          • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

        • The index alias to update when the index rolls over. Specify when using a policy that contains a rollover action. When the index rolls over, the alias is updated to reflect that the index is no longer the write index. For more information about rolling indices, see Rollover.

        • prefer_ilm boolean | string

          Preference for the system that manages a data stream backing index (preferring ILM when both ILM and DLM are applicable for an index).

      • creation_date number | string

        Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

        Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

      • creation_date_string string | number

        A date and time, either as a string whose format can depend on the context (defaulting to ISO 8601), or a number of milliseconds since the Epoch. Elasticsearch accepts both as input, but will generally output a string representation.

      • uuid string
      • version object
        Hide version attributes Show version attributes object
      • translog object
        Hide translog attributes Show translog attributes object

      • Configure custom similarity settings to customize how search results are scored.

      • mapping object
        Hide mapping attributes Show mapping attributes object
        • coerce boolean
        • Hide total_fields attributes Show total_fields attributes object
          • limit number | string

            The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

          • ignore_dynamic_beyond_limit boolean | string

            This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

        • depth object
          Hide depth attribute Show depth attribute object
          • limit number

            The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

        • Hide nested_fields attribute Show nested_fields attribute object
          • limit number

            The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

        • Hide nested_objects attribute Show nested_objects attribute object
          • limit number

            The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

        • Hide field_name_length attribute Show field_name_length attribute object
          • limit number

            Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

        • Hide dimension_fields attribute Show dimension_fields attribute object
          • limit number

            [preview] This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

        • source object
          Hide source attribute Show source attribute object
          • mode string Required

            Values are disabled, stored, or synthetic.

      • Hide indexing.slowlog attributes Show indexing.slowlog attributes object
        • level string
        • source number

          • index object
            Hide index attributes Show index attributes object
            • warn string

      • Hide indexing_pressure attribute Show indexing_pressure attribute object
        • memory object Required
          Hide memory attribute Show memory attribute object
          • limit number

            Number of outstanding bytes that may be consumed by indexing requests. When this limit is reached or exceeded, the node will reject new coordinating and primary operations. When replica operations consume 1.5x this limit, the node will reject new replica operations. Defaults to 10% of the heap.

      • store object
        Hide store attributes Show store attributes object
        • type string Required

        • allow_mmap boolean

          You can restrict the use of the mmapfs and the related hybridfs store type via the setting node.store.allow_mmap. This is a boolean setting indicating whether or not memory-mapping is allowed. The default is to allow it. This setting is useful, for example, if you are in an environment where you can not control the ability to create a lot of memory maps so you need disable the ability to use memory-mapping.

    • defaults object Additional properties
      Hide defaults attributes Show defaults attributes object
      • index object Additional properties
      • mode string

        Hide sort attributes Show sort attributes object
      • Values are true, false, or checksum.

      • codec string
      • routing_partition_size number | string

        Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

        Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

      • auto_expand_replicas string | null

        One of:
      • merge object
        Hide merge attribute Show merge attribute object

        • indexing_complete boolean | string

          Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

          Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

        • If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

        • Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

        • step object
          Hide step attribute Show step attribute object
          • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

        • The index alias to update when the index rolls over. Specify when using a policy that contains a rollover action. When the index rolls over, the alias is updated to reflect that the index is no longer the write index. For more information about rolling indices, see Rollover.

        • prefer_ilm boolean | string

          Preference for the system that manages a data stream backing index (preferring ILM when both ILM and DLM are applicable for an index).

      • creation_date number | string

        Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

        Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

      • creation_date_string string | number

        A date and time, either as a string whose format can depend on the context (defaulting to ISO 8601), or a number of milliseconds since the Epoch. Elasticsearch accepts both as input, but will generally output a string representation.

        Hide mapping attributes Show mapping attributes object
        • coerce boolean
        • Hide total_fields attributes Show total_fields attributes object
          • limit number | string

            The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

          • ignore_dynamic_beyond_limit boolean | string

            This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

        • depth object
          Hide depth attribute Show depth attribute object
          • limit number

            The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

        • Hide nested_fields attribute Show nested_fields attribute object
          • limit number

            The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

        • Hide nested_objects attribute Show nested_objects attribute object
          • limit number

            The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

        • Hide field_name_length attribute Show field_name_length attribute object
          • limit number

            Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

        • Hide dimension_fields attribute Show dimension_fields attribute object
          • limit number

            [preview] This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

Create or update an alias

POST /{index}/_aliases/{name}

Adds a data stream or index to an alias.

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams or indices to add. Supports wildcards (*). Wildcard patterns that match both data streams and indices return an error.

  • name string Required

    Alias to update. If the alias doesn’t exist, the request creates it. Index alias names support date math.

Query parameters

  • Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

  • timeout string

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

application/json

Body

  • filter object

    An Elasticsearch Query DSL (Domain Specific Language) object that defines a query.

    External documentation
  • If true, sets the write index or data stream for the alias. If an alias points to multiple indices or data streams and is_write_index isn’t set, the alias rejects write requests. If an index alias points to one index and is_write_index isn’t set, the index automatically acts as the write index. Data stream aliases don’t automatically set a write data stream, even if the alias points to one data stream.

  • routing string

Responses

  • 200 application/json
    Hide response attribute Show response attribute object
    • acknowledged boolean Required

      For a successful response, this value is always true. On failure, an exception is returned instead.

Get aliases

GET /_alias/{name}

Retrieves information for one or more data stream or index aliases.

Path parameters

  • name string | array[string] Required

    Comma-separated list of aliases to retrieve. Supports wildcards (*). To retrieve all aliases, omit this parameter or use * or _all.

Query parameters

  • If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

  • If false, the request returns an error if it targets a missing or closed index.

  • local boolean Deprecated

    If true, the request retrieves information from the local node only.

            External documentation
          • Value used to route indexing operations to a specific shard. If specified, this overwrites the routing value for indexing operations.

          • If true, the index is the write index for the alias.

          • routing string

            Value used to route indexing and search operations to a specific shard.

          • Value used to route search operations to a specific shard. If specified, this overwrites the routing value for search operations.

          • is_hidden boolean

            If true, the alias is hidden. All indices for the alias must have the same is_hidden value.

Flushing a data stream or index is the process of making sure that any data that is currently only stored in the transaction log is also permanently stored in the Lucene index. When restarting, Elasticsearch replays any unflushed operations from the transaction log into the Lucene index to bring it back into the state that it was in before the restart. Elasticsearch automatically triggers flushes as needed, using heuristics that trade off the size of the unflushed transaction log against the cost of performing each flush.

After each operation has been flushed it is permanently stored in the Lucene index. This may mean that there is no need to maintain an additional copy of it in the transaction log. The transaction log is made up of multiple files, called generations, and Elasticsearch will delete any generation files when they are no longer needed, freeing up disk space.

It is also possible to trigger a flush on one or more indices using the flush API, although it is rare for users to need to call this API directly. If you call the flush API after indexing some documents then a successful response indicates that Elasticsearch has flushed all the documents that were indexed before the flush API was called.

Query parameters

  • If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

  • force boolean

    If true, the request forces a flush even if there are no changes to commit to the index.

  • If false, the request returns an error if it targets a missing or closed index.

  • If true, the flush operation blocks until execution when another flush operation is running. If false, Elasticsearch returns an error if you request a flush when another flush operation is running.

Update index settings

PUT /_settings

Changes dynamic index settings in real time. For data streams, index setting changes are applied to all backing indices by default.

To revert a setting to the default value, use a null value. The list of per-index settings that can be updated dynamically on live indices can be found in index module documentation. To preserve existing settings from being updated, set the preserve_existing parameter to true.

NOTE: You can only define new analyzers on closed indices. To add an analyzer, you must close the index, define the analyzer, and reopen the index. You cannot close the write index of a data stream. To update the analyzer for a data stream's write index and future backing indices, update the analyzer in the index template used by the stream. Then roll over the data stream to apply the new analyzer to the stream's write index and future backing indices. This affects searches and any new data added to the stream after the rollover. However, it does not affect the data stream's backing indices or their existing data. To change the analyzer for existing backing indices, you must create a new data stream and reindex your data into it.

Query parameters

  • If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden.

  • If true, returns settings in flat format.

  • If true, returns settings in flat format.

  • Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

  • If true, existing index settings remain unchanged.

  • timeout string

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

application/json

Body Required

  • index object Additional properties
  • mode string
  • Hide soft_deletes attributes Show soft_deletes attributes object
    • enabled boolean

      Indicates whether soft deletes are enabled on the index.

    • Hide retention_lease attribute Show retention_lease attribute object
      • period string Required

        A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • sort object
    Hide sort attributes Show sort attributes object
  • Values are true, false, or checksum.

  • codec string
  • routing_partition_size number | string

    Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

    Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

  • auto_expand_replicas string | null

    One of:
  • merge object
    Hide merge attribute Show merge attribute object
  • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • blocks object
    Hide blocks attributes Show blocks attributes object
  • analyze object
    Hide analyze attribute Show analyze attribute object
  • Hide highlight attribute Show highlight attribute object
  • routing object
    Hide routing attributes Show routing attributes object
  • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • Hide lifecycle attributes Show lifecycle attributes object
    • name string
    • indexing_complete boolean | string

      Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

      Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

    • If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

    • Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

    • step object
      Hide step attribute Show step attribute object
      • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

    • The index alias to update when the index rolls over. Specify when using a policy that contains a rollover action. When the index rolls over, the alias is updated to reflect that the index is no longer the write index. For more information about rolling indices, see Rollover.

    • prefer_ilm boolean | string

      Preference for the system that manages a data stream backing index (preferring ILM when both ILM and DLM are applicable for an index).

  • creation_date number | string

    Some APIs will return values such as numbers also as a string (notably epoch timestamps). This behavior is used to capture this behavior while keeping the semantics of the field type.

    Depending on the target language, code generators can keep the union or remove it and leniently parse strings to the target type.

  • creation_date_string string | number

    A date and time, either as a string whose format can depend on the context (defaulting to ISO 8601), or a number of milliseconds since the Epoch. Elasticsearch accepts both as input, but will generally output a string representation.

  • uuid string
  • version object
    Hide version attributes Show version attributes object
  • translog object
    Hide translog attributes Show translog attributes object
  • Hide query_string attribute Show query_string attribute object
  • analysis object
    Hide analysis attributes Show analysis attributes object
  • settings object Additional properties
  • Hide time_series attributes Show time_series attributes object
  • queries object
    Hide queries attribute Show queries attribute object
    • cache object
      Hide cache attribute Show cache attribute object
  • Configure custom similarity settings to customize how search results are scored.

  • mapping object
    Hide mapping attributes Show mapping attributes object
    • coerce boolean
    • Hide total_fields attributes Show total_fields attributes object
      • limit number | string

        The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

      • ignore_dynamic_beyond_limit boolean | string

        This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

    • depth object
      Hide depth attribute Show depth attribute object
      • limit number

        The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

    • Hide nested_fields attribute Show nested_fields attribute object
      • limit number

        The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

    • Hide nested_objects attribute Show nested_objects attribute object
      • limit number

        The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

    • Hide field_name_length attribute Show field_name_length attribute object
      • limit number

        Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

    • Hide dimension_fields attribute Show dimension_fields attribute object
      • limit number

        [preview] This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

    • source object
      Hide source attribute Show source attribute object
      • mode string Required

        Values are disabled, stored, or synthetic.

  • Hide indexing.slowlog attributes Show indexing.slowlog attributes object
    • level string
    • source number
    • reformat boolean
    • Hide threshold attribute Show threshold attribute object
      • index object
        Hide index attributes Show index attributes object
        • warn string

          A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

        • info string

          A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

        • debug string

          A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

        • trace string

          A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • Hide indexing_pressure attribute Show indexing_pressure attribute object
    • memory object Required
      Hide memory attribute Show memory attribute object
      • limit number

        Number of outstanding bytes that may be consumed by indexing requests. When this limit is reached or exceeded, the node will reject new coordinating and primary operations. When replica operations consume 1.5x this limit, the node will reject new replica operations. Defaults to 10% of the heap.

  • store object
    Hide store attributes Show store attributes object
    • type string Required

    • allow_mmap boolean

      You can restrict the use of the mmapfs and the related hybridfs store type via the setting node.store.allow_mmap. This is a boolean setting indicating whether or not memory-mapping is allowed. The default is to allow it. This setting is useful, for example, if you are in an environment where you can not control the ability to create a lot of memory maps so you need disable the ability to use memory-mapping.

Create an inference endpoint Added in 8.11.0

PUT /_inference/{inference_id}

When you create an inference endpoint, the associated machine learning model is automatically deployed if it is not already running. After creating the endpoint, wait for the model deployment to complete before using it. To verify the deployment status, use the get trained model statistics API. Look for "state": "fully_allocated" in the response and ensure that the "allocation_count" matches the "target_allocation_count". Avoid creating multiple endpoints for the same model unless required, as each endpoint consumes significant resources.

IMPORTANT: The inference APIs enable you to use certain services, such as built-in machine learning models (ELSER, E5), models uploaded through Eland, Cohere, OpenAI, Mistral, Azure OpenAI, Google AI Studio, Google Vertex AI, Anthropic, Watsonx.ai, or Hugging Face. For built-in models and models uploaded through Eland, the inference APIs offer an alternative way to use and manage trained models. However, if you do not plan to use the inference APIs to use these models or if you want to use non-NLP models, use the machine learning trained model APIs.
