ivanyu opened a new pull request, #19850: URL: https://github.com/apache/kafka/pull/19850
According to KIP-1123, this commit adds the support for rack-aware partitioning to `BuiltInPartitioner`. It comes with two new configs for the producer: `partitioner.rack.aware` and `client.rack`, which allows enabling the new behavior. Apart from the added unit tests, the desired behavior was tested by `kafka-producer-perf-test.sh` with an existing and a non-existing rack against a 4 node cluster with two racks and 12-partition topic: ```shell ./kafka_2.13-4.1.0-SNAPSHOT/bin/kafka-producer-perf-test.sh --topic test-topic --num-records 100000 --throughput -1 --record-size 1 --producer-props bootstrap.servers=127.0.0.1:9092 client.rack=rack0 partitioner.rack.aware=true ``` Delete this text and replace it with a detailed description of your change.
