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!
