Hi Everyone, I discovered yesterday completely by accident. When I went from writing to 10 topics each with 10 partitions to 10 topics each with 2 partitions--all other config params are the same--my write throughput almost doubled! I was not expecting this as I've always thought--and, admittedly, I am still coming up to speed on Kafka--that increasing parallelism via increasing the number of partitions and/or topics would increase write throughput. I was actually experimenting going from 10 partitions per topic to 20 partitions in an effort to increase throughput but stumbled upon 10X2.
Important notes: 1. Replication factor is 1 2. async producer 3. request.required.acks is 1 Any ideas? --John
