Hi,  
I'm aware of two parameters which appear relevant to controlling how long a cluster will wait before reallocation shards when I node goes down:

- index.unassigned.node\_left.delayed\_timeout
- gateway.recover\_after\_time

Can I ask, what is the difference between these parameters? And do they impact each other?

Regards,  
David

Recover after applies only after a cluster restart, delayed is more for single node/rolling restarts.
