== Managing Indices
|
|
|
|
*Index Management* enables you to view index settings,
|
|
mappings, and statistics and perform index-level operations.
|
|
These include refreshing, flushing, clearing the cache, force merging segments,
|
|
freezing indices, and more. *Index Management* provides a convenient way to
|
|
perform bulk operations on multiple indices.
|
|
|
|
To access this feature, go to *Management > {es} > Index Management*.
|
|
If security is enabled,
|
|
you must have the `monitor` cluster privilege and the `view_index_metadata`
|
|
and `manage` index privileges to view the data. See
|
|
{xpack-ref}/security-privileges.html[Security Privileges] for more
|
|
information.
|
|
|
|
*Index Management* uses badges to make users aware when an index is {ref}/frozen-indices.html[frozen],
|
|
a {ref}/ccr-put-follow.html[follower index],
|
|
or a {ref}/rollup-get-rollup-index-caps.html[rollup index].
|
|
Clicking a badge filters for all indices of that type.

|
|
|
Clicking the name of an index displays the index summary and provides access to
|
|
the index settings, mapping, and statistics.
|
|
|
|
From the *Manage* menu, you can perform these index-level operations on either
|
|
a single or multiple indices:
|
|
|
|
* *Close the index*. Blocks the index from read/write operations.
|
|
A closed index exists in the cluster, but doesn't consume resources
|
|
other than disk space. If you reopen a closed index, it goes through the
|
|
normal recovery process.
|
|
|
|
* *Force merge the index*. Reduces the number of segments in your shard by
|
|
merging smaller files and clearing deleted ones. Only force merge a read-only index.
|
|
|
|
* *Refresh the index*. Writes the operations in the indexing buffer to the
|
|
filesystem cache. This is automatically done once per second. Forcing a manual
|
|
refresh is useful during testing, but should not be routinely done in
|
|
production because it has a performance impact.
|
|
|
|
* *Clear the index cache*. Clears all caches associated with the index.
|
|
|
|
* *Flush the index*. Frees memory by syncing the filesystem cache to disk and
|
|
clearing the cache. Once the sync is complete, the internal transaction log is reset.
|
|
|
|
* *Freeze the index*. Makes the index read-only and reduces its memory footprint
|
|
by moving shards to disk. {ref}/frozen-indices.html[Frozen indices] remain
|
|
searchable, but queries take longer.
|
|
|
|
* *Delete the index*. Permanently removes the index and all of it's documents.
|
|
|
|
* *Add an lifecycle policy*. Specifies a policy for managing the lifecycle of the
|
|
index.
