IVM is not new, but the DBSP (2022) perspective is relatively new for databases (where the classic literature is from the 70s and 80s).

It is misleading to say that IVM reduces the cost of view updates from O(n) to O(1). While that is not technically incorrect, for any nontrivial query (e.g anything with an index join) the cost of a view update will be smaller than the original query but not constant time.

Also, the tone of “newfangled” was not dismissive in the context of an article praising IVM. At worst, it was sarcastic; I interpreted it as teasing.

I do research related to IVM / DBSP.
