==== {api-prereq-title}
|
|
|
|
* If the {es} {security-features} are enabled, you must have `write`, `monitor`,
|
|
and `manage_follow_index` index privileges for the follower index. You must have
|
|
`read` and `monitor` index privileges for the leader index. You must also have
|
|
`manage_ccr` cluster privileges on the cluster that contains the follower index.
|
|
For more information, see

{stack-ov}/security-privileges.html[Security privileges].

[[ccr-put-follow-desc]]
|
|
==== {api-description-title}
|
|
|
|
This API creates a new follower index that is configured to follow the
|
|
referenced leader index. When this API returns, the follower index exists, and
|
|
{ccr} starts replicating operations from the leader index to the follower index.
|

|
|
`wait_for_active_shards`::
|
|
(Optional, integer) Specifies the number of shards to wait on being active before
|
|
responding. This defaults to waiting on none of the shards to be active. A
|
|
shard must be restored from the leader index being active. Restoring a
|
|
follower shard requires transferring all the remote Lucene segment files to
|
|
the follower index.
