== Open / Close Index API
|
|
|
|
The open and close index APIs allow to close an index, and later on
|
|
opening it. A closed index has almost no overhead on the cluster (except
|
|
for maintaining its metadata), and is blocked for read/write operations.
|
|
A closed index can be opened which will then go through the normal
|
|
recovery process.
|
|
|
|
The REST endpoint is `/{index}/_close` and `/{index}/_open`. For
|
|
example:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
POST /my_index/_close
|
|
|
|
POST /my_index/_open
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[s/^/PUT my_index\n/]
|
|
|
|
It is possible to open and close multiple indices. An error will be 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`.
