Close index APIedit
Closes an index.
POST /twitter/_close

POST /<index>/_close
Descriptionedit
You use the close index API to close open indices.
A closed index is blocked for read/write operations and does not allow all operations that opened indices allow. It is not possible to index documents or to search for documents in a closed index. This allows closed indices to not have to maintain internal data structures for indexing or searching documents, resulting in a smaller overhead on the cluster.
When opening or closing an index, the master is responsible for restarting the index shards to reflect the new state of the index. The shards will then go through the normal recovery process. The data of opened/closed indices is automatically replicated by the cluster to ensure that enough shard copies are safely kept around at all times.
You can open and close multiple indices. An error is thrown
if the request explicitly refers to a missing index. This behaviour can be
disabled using the ignore_unavailable=true parameter.
All indices can be opened or closed at once using _all as the index name
or specifying patterns that identify them all (e.g. *).
Identifying indices via wildcards or _all can be disabled by setting the
action.destructive_requires_name flag in the config file to true.
This setting can also be changed via the cluster update settings api.
Closed indices consume a significant amount of disk-space which can cause problems in managed environments. Closing indices can be disabled via the cluster settings
API by setting cluster.indices.close.enable to false. The default is true.
Wait For active shardsedit
Because opening or closing an index allocates its shards, the
wait_for_active_shards setting on
index creation applies to the _open and _close index actions as well.
Path parametersedit
-
<index> -
(Optional, string) Comma-separated list or wildcard expression of index names used to limit the request.
To close all indices, use
_allor*. To disallow the closing of indices with_allor wildcard expressions, change theaction.destructive_requires_namecluster setting totrue. You can update this setting in theelasticsearch.ymlfile or using the cluster update settings API.
Query parametersedit
-
allow_no_indices -
(Optional, boolean) If
true, the request does not return an error if a wildcard expression or_allvalue retrieves only missing or closed indices.This parameter also applies to index aliases that point to a missing or closed index.
Defaults to
true. -
expand_wildcards -
(Optional, string) Controls what kind of indices that wildcard expressions can expand to. Multiple values are accepted when separated by a comma, as in
open,hidden. Valid values are:-
all - Expand to open and closed indices, including hidden indices.
-
open - Expand only to open indices.
-
closed - Expand only to closed indices.
-
hidden -
Expansion of wildcards will include hidden indices.
Must be combined with
open,closed, or both. -
none - Wildcard expressions are not accepted.
Defaults to
open. -
-
ignore_unavailable -
(Optional, boolean) If
true, missing or closed indices are not included in the response. Defaults tofalse. -
wait_for_active_shards -
(Optional, string) The number of shard copies that must be active before proceeding with the operation. Set to
allor any positive integer up to the total number of shards in the index (number_of_replicas+1). Default: 1, the primary shard.See Active shards.
-
master_timeout -
(Optional, time units) Specifies the period of time to wait for
a connection to the master node. If no response is received before the timeout
expires, the request fails and returns an error. Defaults to
30s. -
timeout -
(Optional, time units) Specifies the period of time to wait for
a response. If no response is received before the timeout expires, the request
fails and returns an error. Defaults to
30s.
Examplesedit
The following example shows how to close an index:
POST /my_index/_close
The API returns following response:
{
"acknowledged" : true,
"shards_acknowledged" : true,
"indices" : {
"my_index" : {
"closed" : true
}
}
}
