=== Put Mapping API

[[java-rest-high-put-mapping-request]]
==== Put Mapping Request

A `PutMappingRequest` requires an `index` argument, and a type:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-mapping-request]
--------------------------------------------------
<1> The index to add the mapping to
<2> The type to create (or update)

==== Mapping source
A description of the fields to create on the mapping; if not defined, the mapping will default to empty.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-mapping-request-source]
--------------------------------------------------
<1> The mapping source provided as a `String`

==== Providing the mapping source
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-mapping-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-mapping-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-mapping-shortcut]
--------------------------------------------------
<1> Mapping source provided as `Object` key-pairs, which gets converted to
JSON format

==== Optional arguments
The following arguments can optionally be provided:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-mapping-request-timeout]
--------------------------------------------------
<1> Timeout to wait for the all the nodes to acknowledge the index creation as a `TimeValue`
<2> Timeout to wait for the all the nodes to acknowledge the index creation as a `String`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-mapping-request-masterTimeout]
--------------------------------------------------
<1> Timeout to connect to the master node as a `TimeValue`
<2> Timeout to connect to the master node as a `String`

[[java-rest-high-put-mapping-sync]]
==== Synchronous Execution

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-mapping-execute]
--------------------------------------------------

[[java-rest-high-put-mapping-async]]
==== Asynchronous Execution

The asynchronous execution of a put mappings request requires both the `PutMappingRequest`
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-mapping-execute-async]
--------------------------------------------------
<1> The `PutMappingRequest` 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 `PutMappingResponse` looks like:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-mapping-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-mapping-response]]
==== Put Mapping Response

The returned `PutMappingResponse` allows to retrieve information about the executed
 operation as follows:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[put-mapping-response]
--------------------------------------------------
<1> Indicates whether all of the nodes have acknowledged the request
