=== Delete API

[[java-rest-high-document-delete-request]]
==== Delete Request

A `DeleteRequest` requires the following arguments:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-request]
--------------------------------------------------
<1> Index
<2> Type
<3> Document id

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

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-request-routing]
--------------------------------------------------
<1> Routing value

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-request-timeout]
--------------------------------------------------
<1> Timeout to wait for primary shard to become available as a `TimeValue`
<2> Timeout to wait for primary shard to become available as a `String`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-request-refresh]
--------------------------------------------------
<1> Refresh policy as a `WriteRequest.RefreshPolicy` instance
<2> Refresh policy as a `String`

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-request-version]
--------------------------------------------------
<1> Version

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-request-version-type]
--------------------------------------------------
<1> Version type

[[java-rest-high-document-delete-sync]]
==== Synchronous Execution

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

[[java-rest-high-document-delete-async]]
==== Asynchronous Execution

The asynchronous execution of a delete request requires both the `DeleteRequest`
instance and an `ActionListener` instance to be passed to the asynchronous
method:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-execute-async]
--------------------------------------------------
<1> The `DeleteRequest` 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 `DeleteResponse` looks like:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-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-document-delete-response]]
==== Delete Response

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

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-response]
--------------------------------------------------
<1> Handle the situation where number of successful shards is less than
total shards
<2> Handle the potential failures


It is also possible to check whether the document was found or not:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-notfound]
--------------------------------------------------
<1> Do something if the document to be deleted was not found

If there is a version conflict, an `ElasticsearchException` will
be thrown:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/CRUDDocumentationIT.java[delete-conflict]
--------------------------------------------------
<1> The raised exception indicates that a version conflict error was returned
