we are using `sentinel failover` to manually switch master to slave when
upgrading or migrating online.
we are aware that there is a gap between redis-master and redis-slave
(becase of the async replication).
to ensure that this gap caused no critical issue, we need to observe app
behavior, check app logs.
so i wonder if there is a 'safer' way to manually switch master .
BTW, we are using a redis 2.8 fork.
