Use Full Metrics in spout and bolt by default (#1834) Basic SpoutMetrics and BoltMetrics are optimized for performance rather than for debugging. Enable Full Metrics by default can provide more insights during debugging. It is also pushed from Product-Safety team from Twitter, which requires more debugging info. The performance hurt will be negligible for production topology compared with actual workload: it will add only a few java hashmap accessing on every execute(). Test on LocalScheduler.
Heron is realtime analytics platform developed by Twitter. It is the direct successor of Apache Storm, built to be backwards compatible with Storm's topology API but with a wide array of architectural improvements.
For more information:
We recently merged updates to run Heron natively using Mesos in AWS, Mesos/Aurora in AWS, and locally on a laptop.
We also added beta testing for Apache YARN support using Apache REEF, in addition to the Simple Linux Utility for Resource Management (SLURM).
We are working to add support for Mesosphere DC/OS and Kubernetes. We will continue to post updates as we progress.
The official documentation for Heron is located at heronstreaming.io. To contribute to documentation, build and run the documentation locally. More information can be found in the documentation README.
