[[java-rest-high-create-index-request]]
|
|
==== Create Index Request
|
|
|
|
A `CreateIndexRequest` requires an `index` argument:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]

|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[create-index-request]
|
|
--------------------------------------------------
|
|
<1> The index to create
|
|
|
|
==== Index settings
|
|
Each index created can have specific settings associated with it.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]

|
|
|
[[java-rest-high-create-index-request-mappings]]
|
|
==== Index mappings
|
|
An index may be created with mappings for its document types
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|

--------------------------------------------------
|
|
<1> Mapping source provided as a `Map` which gets automatically converted
|
|

--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[create-index-mappings-xcontent]

|
--------------------------------------------------

|
|
built-in helpers to generate JSON content

|
|
--------------------------------------------------
|
|
<1> Mapping source provided as `Object` key-pairs, which gets converted to
|
|
JSON format
|
|
|
|
==== Index aliases
|
|
Aliases can be set at index creation time
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[create-index-request-aliases]
|
|
--------------------------------------------------
|
|
<1> The alias to define
|
|
|
|
==== 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[create-index-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[create-index-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[create-index-request-masterTimeout]
|
|
--------------------------------------------------
|
|
<1> Timeout to connect to the master node as a `TimeValue`
|
|
<2> Timeout to connect to the master node as a `String`
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[create-index-request-waitForActiveShards]
|
|
--------------------------------------------------
|
|
<1> The number of active shard copies to wait for before the create index API returns a
|
|
response, as an `int`
|
|
<2> The number of active shard copies to wait for before the create index API returns a
|
|
response, as an `ActiveShardCount`
|
|
|
|
[[java-rest-high-create-index-sync]]
|
|
==== Synchronous Execution
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[create-index-execute]
|
|
--------------------------------------------------
|
|
|
|
[[java-rest-high-create-index-async]]
|
|
==== Asynchronous Execution
|
|
|
|
The asynchronous execution of a create index request requires both the `CreateIndexRequest`
|
|
instance and an `ActionListener` instance to be passed to the asynchronous
|
|
method:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[create-index-execute-async]
|
|
--------------------------------------------------
|
|
<1> The `CreateIndexRequest` 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 `CreateIndexResponse` looks like:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[create-index-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-create-index-response]]
|
|
==== Create Index Response
|
|
|
|
The returned `CreateIndexResponse` allows to retrieve information about the executed
|
|
operation as follows:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[create-index-response]
|
|
--------------------------------------------------
|
|
<1> Indicates whether all of the nodes have acknowledged the request
|
|
<2> Indicates whether the requisite number of shard copies were started for each shard in the index before timing out
|
