Sriharsha Chintalapani updated STORM-815: ----------------------------------------- Priority: Major (was: Blocker) > Auto tuning topologies based on user submitted SLA > -------------------------------------------------- > > Key: STORM-815 > URL: https://issues.apache.org/jira/browse/STORM-815 > Project: Apache Storm > Issue Type: New Feature > Reporter: Read Sprabery > > Hi all – not sure if this is the place for this or not, so please feel free > to move this ticket around. > I have been working on making Storm SLA aware and wanted to create a ticket > focused on auto-tuning of submitted topologies. Having talked with [~revans2] > , I think this feature will go a long way in improving the usability of Storm. > This will be particularly useful as more abstractions are developed on top of > Storm and developers move further away from the internals of topologies with > systems like Summingbird (https://github.com/twitter/summingbird). Storm > already has the majority of the metrics required to made decisions regarding > the stability of a given stream in Zookeeper; these can be used to decide if > a given SLA is being met. > The system I'm working on functions externally to Storm, getting measurements > from the Thrift interface and then performing parallelism level tuning > through the “rebalance” command. If the community is interested, I can upload > a document in the upcoming weeks highlighting the challenges and benefits of > an auto-tuning system in Storm and that can serve as a first start for > developing an auto-tuning scheduler. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
