Hi,

I'm testing with cross cluster replication. Question:

- What if the leader index is unavailable, the follower index will not be updated. When the leader index is active again, CCR will be running again? No manual task?
- If the leader index is corrupt and recreated, the CCR config needs to be reconfigured?
- if the leader index is down, the search call's (REST, kibana visuals, ..) can still happen on the follower index without any manual action?
