=== Update API
|
|
|
|
[[java-rest-high-document-update-request]]
|
|
==== Update Request
|
|
|
|
An `UpdateRequest` requires the following arguments:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-request]
|
|
--------------------------------------------------
|
|
<1> Index
|
|
<2> Type
|
|
<3> Document id
|
|
|
|
The Update API allows to update an existing document by using a script
|
|
or by passing a partial document.
|
|
|
|
==== Updates with a script
|
|
The script can be provided as an inline script:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-request-with-inline-script]
|
|
--------------------------------------------------
|
|
<1> Script parameters provided as a `Map` of objects
|
|
<2> Create an inline script using the `painless` language and the previous parameters
|
|
<3> Sets the script to the update request
|
|
|
|
Or as a stored script:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-request-with-stored-script]
|
|
--------------------------------------------------
|
|
<1> Reference to a script stored under the name `increment-field` in the `painless` language
|
|
<2> Sets the script in the update request
|
|
|
|
==== Updates with a partial document
|
|
When using updates with a partial document, the partial document will be merged with the
|
|
existing document.
|
|
|
|
The partial document can be provided in different ways:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-request-with-doc-as-string]
|
|
--------------------------------------------------
|
|
<1> Partial document source provided as a `String` in JSON format
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-request-with-doc-as-map]
|
|
--------------------------------------------------
|
|
<1> Partial document source provided as a `Map` which gets automatically converted
|
|
to JSON format
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-request-with-doc-as-xcontent]
|
|
--------------------------------------------------
|
|
<1> Partial document source provided as an `XContentBuilder` object, the Elasticsearch
|
|
built-in helpers to generate JSON content
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-request-shortcut]
|
|
--------------------------------------------------
|
|
<1> Partial document source provided as `Object` key-pairs, which gets converted to
|
|
JSON format
|
|
|
|
==== Upserts
|
|
If the document does not already exist, it is possible to define some content that
|
|
will be inserted as a new document using the `upsert` method:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-request-upsert]
|
|
--------------------------------------------------
|
|
<1> Upsert document source provided as a `String`
|
|
|
|
Similarly to the partial document updates, the content of the `upsert` document
|
|
can be defined using methods that accept `String`, `Map`, `XContentBuilder` or
|
|
`Object` key-pairs.
|
|
|
|
==== Optional arguments

The following arguments can optionally be provided:
|
|
|

[[java-rest-high-document-update-sync]]
|
|
==== Synchronous Execution
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-execute]
|
|
--------------------------------------------------
|
|
|
|
[[java-rest-high-document-update-async]]
|
|
==== Asynchronous Execution
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-execute-async]
|
|
--------------------------------------------------
|
|
<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-update-response]]
|
|
==== Update Response
|
|
|
|
The returned `UpdateResponse` allows to retrieve information about the executed
|
|
operation as follows:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-response]
|
|
--------------------------------------------------
|
|
<1> Handle the case where the document was created for the first time (upsert)
|
|
<2> Handle the case where the document was updated
|
|
<3> Handle the case where the document was deleted
|
|
<4> Handle the case where the document was not impacted by the update,
|
|
ie no operation (noop) was executed on the document
|
|
|
|
When the source retrieval is enabled in the `UpdateRequest`
|
|
through the fetchSource method, the response contains the
|
|
source of the updated document:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-getresult]
|
|
--------------------------------------------------
|
|
<1> Retrieve the updated document as a `GetResult`
|
|
<2> Retrieve the source of the updated document as a `String`
|
|
<3> Retrieve the source of the updated document as a `Map<String, Object>`
|
|
<4> Retrieve the source of the updated document as a `byte[]`
|
|
<5> Handle the scenario where the source of the document is not present in
|
|
the response (this is the case by default)
|
|
|
|
It is also possible to check for shard failures:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-failure]
|
|
--------------------------------------------------
|
|
<1> Handle the situation where number of successful shards is less than
|
|
total shards
|
|
<2> Handle the potential failures
|
|
|
|
When a `UpdateRequest` is performed against a document that does not exist,
|
|
the response has `404` status code, an `ElasticsearchException` gets thrown
|
|
which needs to be handled as follows:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-docnotfound]
|
|
--------------------------------------------------
|
|
<1> Handle the exception thrown because the document not exist
|
|
|
|
If there is a version conflict, an `ElasticsearchException` will
|
|
be thrown:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/CRUDDocumentationIT.java[update-conflict]
|
|
--------------------------------------------------
|
|
<1> The raised exception indicates that a version conflict error was returned.
