|
==== Description
|
||||||
|
|
||||||
|
This API pauses a follower index. When this API returns, the follower index will
|

|
not fetch any additional operations from the leader index. You can resume
|
||||||
|
following with the <<ccr-post-resume-follow,resume follower API>>. Pausing and
|

|
resuming a follower index can be used to change the configuration of the
|

Converts a follower index to a regular index.
|
||||||
|
|
||||||
|
==== Description
|
||||||
|
|
||||||
|
This API stops the following task associated with a follower index and removes
|
||||||
|
index metadata and settings associated with {ccr}. This enables the index to
|
||||||
|
treated as a regular index. The follower index must be paused and closed before
|
||||||
|
invoking the unfollow API.
|
||||||
|
|
||||||
|
NOTE: Currently {ccr} does not support converting an existing regular index to a
|
||||||
|
follower index. Converting a follower index to a regular index is an
|
||||||
|
irreversible operation.

Creates a follower index.

==== Description
|
||||||
|
|
||||||
|
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.
