Hi All,
Anyone knows, how many queue processor can be created in a Pega Cluster?
Thanks,

Each queue processor can process messages across 20 partitions, which means that Queue Processor rules can support up to 20 separate processing threads simultaneously with no conflict

@FerdinanP Very interesting question. I couldn't find anything on the number of topic restrictions in Kafka. So I assume you could create as many queue processors as you want. Plus, there is no way to stop an application from using the standard Queue processor. What number are you at? Are we talking thousands of Queue Processors?

I think there is no upper limit for Queue processor in a cluster. It just boils down to the fact that each cluster can support max of 20 partitions. Also, thread count is not equal to partitions. You can check prconfig/dsm/services/stream/pytopicpartitionscount/default value to check the partition count defined.
Hope this helps
