Support regexes in topic names in ChangeProp
Closed, ResolvedPublic


In JobQueue we have one queue per job type, so we need a separate Kafka topic per job type. For better load distribution we not only should be able to connect a worker to all topics that match some regex (like job_queue.*), but also create a separate RuleExecutor for each of these topics so that the work would be distributed between workers.

Likely there will be a lot of rules in that scenario, so we’d hit the UV_THREADPOOL_SIZE=128 limit, so we’d need to finally wrap up the long-awaited changes to the node kafka driver to avoid that.
