Hi folks, As many of you may be aware, we have been working on the integration between Apache Calcite and Apache Phoenix, in which Calcite is going to replace the existing standalone Phoenix's parser, validator and query planner and Phoenix will continue to focus on runtime features and execution performance. The new integrated Phoenix will have improved SQL compliance, cost-based query planning and better interoperability with other data sources.
After basic feature completion, we are now working to fill in the gap of test pass rate between "calcite" branch ( https://git1-us-west.apache.org/repos/asf?p=phoenix.git;a=shortlog;h=refs/heads/calcite) and "master" branch, and once the gap is closed (or trivial enough) we will switch to "calcite" branch as the new Phoenix "master" branch. As part of this effort, we have a weekly online meeting to sync up status and discuss technical issues. If any of you are interested to learn about our progress or to contribute, we would like to welcome you to join our weekly sync up meeting, happening every Thursday at 9:30am PST at http://www.hydromatic.net/hangout. Thanks, Maryann
