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.
