=== Rollover Index API
|
|
|
|
[id="{upid}-{api}-request"]
|
|
==== Rollover Request
|
|
|
|
The Rollover Index API requires a +{request}+ instance.
|
|
A +{request}+ requires two string arguments at construction time, and
|
|
one or more conditions that determine when the index has to be rolled over:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-request]
|
|
--------------------------------------------------
|
|
<1> The alias (first argument) that points to the index to rollover, and
|
|
the name of the new index in case the rollover operation is performed.
|
|
The new index argument is optional, and can be set to null
|
|
<2> Condition on the age of the index
|
|
<3> Condition on the number of documents in the index
|
|
<4> Condition on the size of the index
|
|
|
|
==== Optional arguments
|
|
The following arguments can optionally be provided:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-request-dryRun]
|
|
--------------------------------------------------
|
|
<1> Whether the rollover should be performed (default) or only simulated
|
|
|
|
["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`
|
|
|
|
["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`
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-request-waitForActiveShards]
|
|
--------------------------------------------------
|
|
<1> Sets the number of active shard copies to wait for before the rollover
|
|
index API returns a response
|
|
<2> Resets the number of active shard copies to wait for to the default value
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-request-settings]
|
|
--------------------------------------------------
|
|
<1> Add the settings to apply to the new index, which include the number of
|
|
shards to create for it
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-request-mapping]
|
|
--------------------------------------------------
|
|
<1> Add the mappings to associate the new index with. See <<java-rest-high-create-index-request-mappings>>
|
|
for examples on the different ways to provide mappings
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests-file}[{api}-request-alias]
|
|
--------------------------------------------------
|
|
<1> Add the aliases to associate the new index with
|
|
|
|
include::../execution.asciidoc[]
|
|
|
|
[id="{upid}-{api}-response"]
|
|
==== Rollover 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
|
|
<3> The name of the old index, eventually rolled over
|
|
<4> The name of the new index
|
|
<5> Whether the index has been rolled over
|
|
<6> Whether the operation was performed or it was a dry run
|
|
<7> The different conditions and whether they were matched or not
|
