We (I work at Materialize) actually do support updates! Our CDC sources support them, as well as any source using an UPSERT envelope (more info here: https://materialize.com/docs/sql/create-source/text-kafka/#u...).

As per your second point, I have a less awkward way for you! Materialize supports a top-k idiom (https://materialize.com/docs/sql/idioms/#top-k-by-group) that is hopefully a bit more clear.



Right, I saw no update in the SQL keyword list, and saw some (I guess old now) talk about Materialize where the speaker mentioned no updates, sorry!


No apologies necessary, we're an active work in progress! (And, hopefully, moving quickly!)
