index_templateobjectrequired -
templateobject -
Template to be applied. It may optionally include an
aliases,mappings, orsettingsconfiguration. -
lifecycleobject -
data_retentionstring -
If defined, every document added to this data stream will be stored at least for this time frame. Any time after this duration the document could be deleted. When empty, every document in this data stream will be stored indefinitely.
-
retention_determined_by -
Configuration source that can influence the retention of a data stream.
-
Values:
data_stream_configurationdefault_global_retentionmax_global_retentiondefault_failures_retention -
downsamplingobject -
The list of downsampling rounds to execute as part of this downsampling configuration
-
downsampling_method -
The method used to downsample the data. There are two options
aggregateandlast_value. It requiresdownsamplingto be defined. Defaults toaggregate. -
Values:
aggregatelast_value -
enabledboolean · default: true -
If defined, it turns data stream lifecycle on/off (
true/false) for this data stream. A data stream lifecycle that's disabled (enabled:false) will have no effect on the data stream. -
frozen_afterstring -
The period after which data stream backing indices are automatically converted to partially mounted searchable snapshots. This field is valid only on main data stream lifecycles and cannot be set on failure-store lifecycles.
-
rolloverobject -
The conditions which will trigger the rollover of a backing index as configured by the cluster setting
cluster.lifecycle.default.rollover. This property is an implementation detail and it will only be retrieved when the query paraminclude_defaultsis set to true. The contents of this field are subject to change. -
aliasesmap string to object -
Aliases to add. If the index template includes a
data_streamobject, these are data stream aliases. Otherwise, these are index aliases. Data stream aliases ignore theindex_routing,routing, andsearch_routingoptions. -
<string>object -
filterQuery -
Query used to limit documents the alias can access.
-
index_routingstring -
Value used to route indexing operations to a specific shard. If specified, this overwrites the
routingvalue for indexing operations. -
If
true, the alias is hidden. All indices for the alias must have the sameis_hiddenvalue. -
mappingsobject -
Mapping for fields in the index. If specified, this mapping can include field names, field data types, and mapping parameters.
-
data_stream_optionsobject -
failure_storeobject -
If defined, it specifies configuration for the failure store of this data stream.
-
enabledboolean · default: true -
If defined, it turns the failure store on/off (
true/false) for this data stream. A data stream failure store that's disabled (enabled:false) will redirect no new failed indices to the failure store; however, it will not remove any existing data from the failure store. -
index_patternsstringrequired -
Array of wildcard (
*) expressions used to match the names of data streams and indices during creation. -
composed_ofstringrequired -
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.
-
versionnumber -
Version number used to manage index templates externally. This number is not automatically generated by Elasticsearch.
-
prioritynumber -
Priority to determine index template precedence when a new data stream or index is created. The index template with the highest priority is chosen. If no priority is specified the template is treated as though it is of priority 0 (lowest priority). This number is not automatically generated by Elasticsearch.
-
_metaobject -
Optional user metadata about the index template. May have any contents. This map is not automatically generated by Elasticsearch.
-
data_streamobject -
If this object is included, the template is used to create data streams and their backing indices. Supports an empty object. Data streams require a matching index template with a
data_streamobject. -
deprecatedboolean -
Marks this index template as deprecated. When creating or updating a non-deprecated index template that uses deprecated components, Elasticsearch will emit a deprecation warning.
-
ignore_missing_component_templatesstring -
A list of component template names that are allowed to be absent.
-
created_dateunion -
Date and time when the index template was created. Only returned if the
humanquery parameter istrue. -
created_date_millisnumber -
Date and time when the index template was created, in milliseconds since the epoch.
