Increasing replication factor reliable?
Is it safe to run this on an active production topic? A topic was created
without a replication factor of 2 and I want to increase it from 1 to 2 to
have fault tolerance.

Hi, i am wondering why the increased replication factor is related to a
partition instead of the topic. Isn't it very hard to manage? Any one can
help me clarify this?

So u have two nodes running where you want to increase the replication
factor 2 because of fault tolerance. That won't be a problem

Yeah - it will increase IO and network utilization by a lot while data is
replication, but it should be safe.
