While running a stress test for a custom processor (~100 topics, ~10,000 messages) we identified a test hotspot with a profiler. A small but surprising amount of time is spent in Pattern.compile while calling pipeInput - this loop recompiles topic patterns every time, which is approximately O(nTopics) * O(nMessages). While normally test code isn't overly concerned with raw performance, this seems like an easy win to speed up test cases without losing anything. -- This is an automated message from the Apache Git Service.
