Body

• allow_auto_create boolean

  This setting overrides the value of the action.auto_create_index cluster setting. If set to true in a template, then indices can be automatically created using that template even if auto-creation of indices is disabled via actions.auto_create_index. If set to false, then indices or data streams matching the template must always be explicitly created, and may never be automatically created.

• index_patterns string | array[string]
• composed_of array[string]

  An ordered list of component template names. Component templates are merged in the order specified, meaning that the last component template specified has the highest precedence.

• template object

  Additional properties are allowed.

  Hide template attributes Show template attributes object

  • aliases object

    Aliases to add. If the index template includes a data_stream object, these are data stream aliases. Otherwise, these are index aliases. Data stream aliases ignore the index_routing, routing, and search_routing options.

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

          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

        Additional properties are allowed.

        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.

      • nested_fields object

        Additional properties are allowed.

        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.

      • nested_objects object

        Additional properties are allowed.

        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.

      • field_name_length object

        Additional properties are allowed.

        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).

      • dimension_fields object

        Additional properties are allowed.

        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.

          • 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.

      • memory object Required

        Additional properties are allowed.

        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

      Additional properties are allowed.

      Hide store attributes Show store attributes object

      • type string Required

        Any of:

        Values are fs, niofs, mmapfs, or hybridfs.
      • 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.

  • lifecycle object

    Additional properties are allowed.

    Hide lifecycle attributes Show lifecycle attributes object

    • data_retention string
