=== Shrink Index API

[id="{upid}-{api}-request"]
==== Resize Request

The Shrink API requires a +{request}+ instance.
A +{request}+ requires two string arguments:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------
<1> The target index (first argument) to shrink the source index (second argument) into

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

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-timeout]
--------------------------------------------------
<1> Timeout to wait for the all the nodes to acknowledge the index is opened
as a `TimeValue`
<2> Timeout to wait for the all the nodes to acknowledge the index is opened
as a `String`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-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-file}[{api}-request-waitForActiveShards]
--------------------------------------------------
<1> The number of active shard copies to wait for before the shrink index API
returns a response, as an `int`
<2> The number of active shard copies to wait for before the shrink index API
returns a response, as an `ActiveShardCount`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-settings]
--------------------------------------------------
<1> The number of shards on the target of the shrink index request
<2> Remove the allocation requirement copied from the source index

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-maxSinglePrimarySize]
--------------------------------------------------
<1> The max single primary shard size of the target index

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-aliases]
--------------------------------------------------
<1> The aliases to associate the target index with

include::../execution.asciidoc[]

[id="{upid}-{api}-response"]
==== Shrink Index Response

The returned +{response}+ allows to retrieve information about the
executed operation as follows:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-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
