Belated follow-up on this thread. Can you talk more about how you manage
this? E.g., how do you ensure that clients continue consuming from the old
cluster until all the messages published to it have been consumed? And
during the transition time, consuming clients consume from both old and new
cluster, right? What hardware/software do you use to gradually shift
publishing from old to new cluster?
We're just now designing and implementing our infrastructure and apps so
would like to get it as right as possible from the beginning. Anyone else
using/recommend other approaches to this problem?
