| <p>The Apache Storm community is pleased to announce that version 1.2.0 has been released and is available from <a href="/downloads.html">the downloads page</a>.</p> |
| |
| <h2 id="apache-kafka-integration-improvements">Apache Kafka Integration Improvements</h2> |
| |
| <p>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 |
| <a href="/releases/1.2.0/storm-kafka-client.html">Kafka client documentation</a></p> |
| |
| <h2 id="new-metrics-reporting-api">New Metrics Reporting API</h2> |
| |
| <p>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 <a href="">Dropwizard Metrics library</a>. 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 <code>org.apache.storm.metrics2.reporters.ScheduledStormReporter</code> class. Additional details can be found in the <a href="/releases/1.2.0/metrics_v2.html">metrics documentation</a>.</p> |
| |
| <h2 id="thanks">Thanks</h2> |
