Re: Controlled shutdown failure, retry settings
A replica is dropped out of ISR if (1) it hasn't issue a fetch request for
some time, or (2) it's behind the leader by some messages. The replica will
be added back to ISR if neither condition is longer true.

The actual value depends on the application. For example, if there is a
spike and the follower can't keep up, the application has to decide whether
to slow down the commit of messages or let the replicas drift apart.

Thanks,
