The Apache Storm community is pleased to announce that version 1.2.0 has been released and is available from the downloads page.
This release includes many improvements to Apache Storm's Kafka integration that improve stability, ease configuration, and expose new features. More details can be found in the Kafka client documentation
This release introduces a new metrics system for reporting internal statistics (e.g. acked, failed, emitted, transferred, disruptor queue metrics, etc.) as well as a new API for user defined metrics based on the popular Dropwizard Metrics library. Apache Storm includes reporters for gathering metrics data with Ganglia, Graphite, JMX, CSV and the console. Additional metrics systems can be integrated by extending the org.apache.storm.metrics2.reporters.ScheduledStormReporter class. Additional details can be found in the metrics documentation.
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.
