Subject kafka streams replication.factor=3 triples the count of tasks for internal topics
Date Tue, 05 Nov 2019 22:45:04 GMT
Hi,

I noticed that by default, replication.factor is 1 for Kafka Streams.
I increased it to 3 as the document suggested.
Before, I have 2 repartition topics and each has 63 partitions. After
increasing to replication 3, those each repartition topic has 63 * 3 =
189 tasks.

Is these behavior expected? I though the replication happened on
broker side, instead of letting client process the tripled traffic.

Or is there any other config I missed?
Thanks for the help!
