Partition replica placement strategy support?

[danthegoodman1]

Is it supported to use something like the in-rack strategy found: https://github.com/segmentio/topicctl#placement-strategies to enable partition replicas and leaders to be placed in the same AZ/rack? Or will it always try to spread them out among the racks?

hi @danthegoodman1 there is a PR at #2975 that will allow an external tool rpk or some other tool to place partitions in specific brokers.

on the roadmap is the ability to expose fine grain affinity and anti-affinity constraint solvers, we haven't started that but we definitely need to.

i think topicctl uses the apis in #2975
