Yeah I can see it being useful when you’ve implemented your own operator, but I also see users making assumptions how some of the built-in operators work and try to change/fix things where they don’t know exactly what they’re doing

The main challenge is always that savepoint and checkpoints can also contain data that hasn’t been emitted to the sink yet. You’re basically looking at committed and uncommitted data from internal state. Is that really interesting for users? Or just the committed part?

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) ❤️

I guess I should be searching for “Apache Flink” when looking for folks to add to the data streaming starter pack.
