Topic config reset on alter
I am using kafka 8.1.1
If you run an alter on a topic to increase the number of partitions the existing configs are removed from the topic. You can confirm this by doing:
bin/kafka-topics.sh —zookeeper localhost —alter —topic topic —config retention.ms=3600000
bin/kafka-topics.sh —zookeeper localhost —describe
> Topic:topic PartitionCount:5 ReplicationFactor:1 Configs:retention.ms=3600000
bin/kafka-topics.sh —zookeeper localhost —alter —topic topic —partitions 10
bin/kafka-topics.sh —zookeeper localhost —describe
> Topic:topic PartitionCount:10 ReplicationFactor:1 Configs:
This feels like a bug to me, where is the best place to report something like this?
