Ha! I don't yet know much about 'incremental computing engines' but Feldera seem to be something I need. Because at some point I inevitably have to create materialized views to speed up some parts of the pipeline. Materialized views are of course a side effect and can become mildly dangerous if you're not careful to destroy/recreate them in time.

I was trying to think of a way to "only update new or changed rows" but it's not trivial. But Feldera seems to do exactly that. So thanks!
