Re: [DISCUSS] Apache Calcite Online Meetup January 2021
Thanks for organizing Stamatis! I enjoyed hearing what others are working on. However, if we do this again I wonder if we could use a regular Zoom meeting instead of a webinar. I think it might be easier to facilitate discussion that way. -- Michael Mior mm...@apache.org Le ven. 22 janv. 2021 à 06:28, Stamatis Zampetakis a écrit : > > Hi everybody, > > Thanks again for attending the meetup and of course big thanks to the > speakers for the great presentations and thoughtful discussion. > > For those interested the recordings are now available on youtube: > https://www.youtube.com/playlist?list=PLUp_iibbIwFF_5xeLRgz4zU33mFRbS5Y6 > > Best, > Stamatis > > On Fri, Jan 15, 2021 at 4:07 AM Chunwei Lei wrote: > > > Ignore my previous email.

To clarify
[jira] [Created] (CALCITE-4475) New Sort SEMI/ANTI Join Transpose optimization
Ruben Q L created CALCITE-4475:
--
Summary: New Sort SEMI/ANTI Join Transpose optimization
Key: CALCITE-4475
URL: https://issues.apache.org/jira/browse/CALCITE-4475
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Ruben Q L
If I am not mistaken, the optimization that is currently applied by
{{SortJoinTransposeRule}} for LEFT and RIGHT joins could also by applied to
SEMI / ANTI joins (it would be very similar to the current LEFT join
optimization).
It is proposed to either improve this rule to cover SEMI / ANTI joins or create
a new dedicated rule for this matter.
