He worked on Uber’s SQL-based stream analytics engine AthenaX which is currently powering over 500+ production real-time data analytics and ML pipelines. As we reflected on these pain points, we thought, there must be a better way. Prior to the Flink as a Service platform, JW’s Video Player team would analyze video player data the day after a release to validate the new code was behaving as expected. The example of taskmanager-query-state-service.yaml can be found in appendix. Over time, two pain points emerged: We found that the optimal way to run these jobs was to chunk incoming data into 20 minute batches. Flink client is used to submit jobs (streaming jobs) to Flink. This approach is not desirable in a modern DevOps setup, where robust Continuous Delivery is achieved through Immutable Infrastructure, i.e. Specifically, we will discuss how we manage the deployment, how we make the platform highly available to support critical real-time business, how we scale the platform to support the entire company, and our experience running the platform in production. Given the numerous permutations of possible player setups and browser versions, testing every single one is not realistic.
