In Elasticsearch, Index API performs the operation at the index level. Removes the assigned lifecycle policy and stops managing the specified index. This will increase the number of open files, so make sure you have enough. Remove policy from index API edit.

Parameters: index – The name of the follower index; body – The name of the leader index and other optional ccr related parameters; wait_for_active_shards – Sets the number of shard copies that must be active before returning. several Elasticsearch makes one copy of the primary shards for each index.
