=== Put Template API

[[java-rest-high-put-template-request]]
|
|
==== Put Index Template Request
|
|
|
|
A `PutIndexTemplateRequest` specifies the `name` of a template and `patterns`
|
|
which controls whether the template should be applied to the new index.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request]
|
|
--------------------------------------------------
|
|
<1> The name of the template
|
|
<2> The patterns of the template
|
|
|
|
==== Settings
|
|
The settings of the template will be applied to the new index whose name matches the
|
|
template's patterns.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-settings]
|
|
--------------------------------------------------
|
|
<1> Settings for this template
|
|
|
|
[[java-rest-high-put-template-request-mappings]]
|
|
==== Mappings
|
|
The mapping of the template will be applied to the new index whose name matches the
|
|
template's patterns.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-mappings-json]
|
|
--------------------------------------------------
|
|
<1> The type to define
|
|
<2> The mapping for this type, provided as a JSON string
|
|
|
|
The mapping source can be provided in different ways in addition to the
|
|
`String` example shown above:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-mappings-map]
|
|
--------------------------------------------------
|
|
<1> Mapping source provided as a `Map` which gets automatically converted
|
|
to JSON format
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-mappings-xcontent]
|
|
--------------------------------------------------
|
|
<1> Mapping source provided as an `XContentBuilder` object, the Elasticsearch
|
|
built-in helpers to generate JSON content
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-mappings-shortcut]
|
|
--------------------------------------------------
|
|
<1> Mapping source provided as `Object` key-pairs, which gets converted to
|
|
JSON format
|
|
|
|
==== Aliases
|
|
The aliases of the template will define aliasing to the index whose name matches the
|
|
template's patterns. A placeholder `{index}` can be used in an alias of a template.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-aliases]
|
|
--------------------------------------------------
|
|
<1> The alias to define
|
|
<2> The alias to define with placeholder
|
|
|
|
==== Order
|
|
In case multiple templates match an index, the orders of matching templates determine
|
|
the sequence that settings, mappings, and alias of each matching template is applied.
|
|
Templates with lower orders are applied first, and higher orders override them.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-order]
|
|
--------------------------------------------------
|
|
<1> The order of the template
|
|
|
|
==== Version
|
|
A template can optionally specify a version number which can be used to simplify template
|
|
management by external systems.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-version]
|
|
--------------------------------------------------
|
|
<1> The version number of the template
|
|
|
|
==== Providing the whole source
|
|
The whole source including all of its sections (mappings, settings and aliases)
|
|
can also be provided:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-whole-source]
|
|
--------------------------------------------------
|
|
<1> The source provided as a JSON string. It can also be provided as a `Map`
|
|
or an `XContentBuilder`.
|
|
|
|
==== Optional arguments
|
|
The following arguments can optionally be provided:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-create]
|
|
--------------------------------------------------
|
|
<1> To force to only create a new template; do not overwrite the existing template
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-request-masterTimeout]
|
|
--------------------------------------------------
|
|
<1> Timeout to connect to the master node as a `TimeValue`
|
|
<2> Timeout to connect to the master node as a `String`
|
|
|

|
==== Synchronous Execution
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-execute]
|
|
--------------------------------------------------
|
|
|
|
[[java-rest-high-put-template-async]]
|
|
==== Asynchronous Execution
|
|
|
|
The asynchronous execution of a put template request requires both the `PutIndexTemplateRequest`
|
|
instance and an `ActionListener` instance to be passed to the asynchronous method:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-execute-async]
|
|
--------------------------------------------------
|
|
<1> The `PutIndexTemplateRequest` to execute and the `ActionListener` to use when
|
|
the execution completes
|
|
|
|
The asynchronous method does not block and returns immediately. Once it is
|
|
completed the `ActionListener` is called back using the `onResponse` method
|
|
if the execution successfully completed or using the `onFailure` method if
|
|
it failed.
|
|
|
|
A typical listener for `PutIndexTemplateResponse` looks like:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-execute-listener]
|
|
--------------------------------------------------
|
|
<1> Called when the execution is successfully completed. The response is
|
|
provided as an argument
|
|
<2> Called in case of failure. The raised exception is provided as an argument
|
|
|
|
[[java-rest-high-put-template-response]]
|
|
==== Put Index Template Response
|
|
|
|
The returned `PutIndexTemplateResponse` allows to retrieve information about the
|
|
executed operation as follows:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-template-response]
|
|
--------------------------------------------------
|
|
<1> Indicates whether all of the nodes have acknowledged the request
