Hi everyone, We are happy to announce that the new multi-stage query engine (called “v2” engine from now on) is entering Beta testing phase. The new v2 engine comes with multi-stage DAG query plan execution capability and many new query features have been added such as inner join, multiple joins, and mix executions with joins and group-bys. Please feel free to try it out by following the instructions below: 1. build Pinot normally on latest master. 2. run Pinot with the v2 engine quickstart:

bin/pinot-admin.sh Quickstart -type MULTI_STAGE

3. run queries by checking the v2 engine selection box (see attachments) We would like to also invite you to join the #C03Q4A11GC9 to discuss the future of the new v2 engine to • share real-world use cases and stories; • file bug reports and other issues/comments during try-out; • collaborate to add more SQL semantic features & performance improvement patches. Thank you!
