client.dns.lookup=”use_all_dns_ips” cache ttl

Hi!

I'm considering to use the following configuration for my producers and
consumers:

client.dns.lookup="use_all_dns_ips"

So that I only have a single DNS entry to manage the list of brokers.

I also have another cluster connected via MirrorMaker 2, which serves as a
failover.

My question is, if I was to change the DNS entry to point to the 2nd
cluster, is there a delay before clients pick up the new A Records due to
caching? If yes, can caching be disabled?

Thank you.
