----------------------------------
Summary: Improve Storm ACK-ing performance
Key: STORM-1539
URL: https://issues.apache.org/jira/browse/STORM-1539
Project: Apache Storm
Issue Type: Bug
Reporter: Roshan Naik
Assignee: Roshan Naik
Profiling a simple speed of light topology, shows that a good chunk of time of
the SpoutOutputCollector.emit() is spent in the clojure reduce() function..
which is part of the ACK-ing logic.
Re-implementing this reduce() logic in java gives a big performance boost in
both in the Spout.nextTuple() and Bolt.execute()
