we may don't need to make sure redis connection is alive in our code

[MayyS]

I have a question about this code snippet. Do we need to implement our own connection keep-alive mechanism in the code?

iam/pkg/storage/redis_cluster.go

Lines 159 to 184 in 819ffde

	again:
	for {
	select {
	case <-ctx.Done():
	return
	case <-tick.C:
	if !shouldConnect() {
	continue
	}
	for _, v := range c {
	if !connectSingleton(v.IsCache, config) {
	redisUp.Store(false)
	goto again
	}
	if !clusterConnectionIsOpen(v) {
	redisUp.Store(false)
	goto again
	}
	}
	redisUp.Store(true)
	}
	}
	}

I noticed a code snippet in the go-redis library that seems to handle connection keep-alive for us.
https://github.com/redis/go-redis/blob/2eb36ad9c874df5d87c320a816a3687286d10786/internal/pool/pool.go#L87-L106
So, I think that we don't need to implement connection keep-alive in our code again. Is my understanding correct?
