=== 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
