|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[index-execute]
|
|
--------------------------------------------------
|
|
|
|
[[java-rest-high-document-index-async]]
|
|
==== Asynchronous Execution
|
|
|
|
The asynchronous execution of an index request requires both the `IndexRequest`
|
|
instance and an `ActionListener` instance to be passed to the asynchronous
|
|
method:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[index-execute-async]
|
|
--------------------------------------------------
|
|
<1> The `IndexRequest` 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 `IndexResponse` looks like:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[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-document-index-response]]
|
|
==== Index Response
|
|
|
|
The returned `IndexResponse` allows to retrieve information about the executed
|
|
operation as follows:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[index-response]
|
|
--------------------------------------------------
|
|
<1> Handle (if needed) the case where the document was created for the first
|
|
time
|
|
<2> Handle (if needed) the case where the document was rewritten as it was
|
|
already existing
|
|
<3> Handle the situation where number of successful shards is less than
|
|
total shards
|
|
<4> Handle the potential failures
|
|
|
|
If there is a version conflict, an `ElasticsearchException` will
|
|
be thrown:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[index-conflict]
|
|
--------------------------------------------------
|
|
<1> The raised exception indicates that a version conflict error was returned
|
|
|
|
Same will happen in case `opType` was set to `create` and a document with
|
|
same index, type and id already existed:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[index-optype]
|
|
--------------------------------------------------
|
|
<1> The raised exception indicates that a version conflict error was returned
