The latest paper from the #1 CMU-DB PhD student @samarchdb.bsky.social is wild compilation magic! He automatically makes UDFs run 300x faster on SQL Server and 1.3x faster on DuckDB.

Very nice: Compact Object Headers targeted as experimental feature to #Java 24! This should yield some nice reduction of the heap size Java apps need. Kudos to Roman Kennke and team!

FLIP-440 with ProcessTableFunction cwiki.apache.org/confluence/p... is probably the #apacheflink FLIP I've been most excited about since the Table API & SQL upgrade FLIP. Having the ability to build your own processing function with the benefits of the SQL ecosystem (query planner, optimizer) ❤️
