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.

Query parameters

allow_no_indices boolean

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.
flat_settings boolean

If true, returns settings in flat format.
ignore_unavailable boolean

If true, returns settings in flat format.
master_timeout string

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.
preserve_existing boolean

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.

  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.

- total_fields object
  
  Additional properties are allowed.
  Hide total_fields attributes Show total_fields attributes object
  
  limit number
  
  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
  
  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.

indexing_pressure object

Additional properties are allowed.
Hide indexing_pressure attribute Show indexing_pressure attribute object
- 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:
  _types:StorageType string _types:StorageType string
  
  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.
