Apache Storm 1.0.1 Released
Posted on May 6, 2016 by P. Taylor Goetz
The Apache Storm community is pleased to announce that version 1.0.1 has been released and is available from the downloads page.
This is a maintenance release that includes a number of important bug fixes that improve Apache Storm's performance, stability and fault tolerance. We encourage users of previous versions to upgrade to this latest release.
This release includes performance improvements to Apache Storm's internal messaging system. The maximum rate at which spouts can emit data has nearly doubled, and performance of inter-task communication has improved.
Special thanks are due to all those who have contributed to Apache Storm -- whether through direct code contributions, documentation, bug reports, or helping other users on the mailing lists. Your efforts are much appreciated.
