> @stoty @virajjasani is this something that Phoenix could use to make better query plans? Most of these statistics are not particularly relevant for Phoenix, as extreme row/cell sizes are less typical in Phoenix's relational model. However, I think this same infrastructure could be extended for key distribution, cardinality, and other statistics that are relevant for query plan optimization. Those would probably need some kind of pluggalble interface where Phoenix can process the rowkeys as its own PK components as the data is collected. Phoenix doesn't really do optimization based on table contents today, so there is a lot of room for improvement. Unfortunately, my knowledge on optimization techniques is also lacking, so I cannot tell whether this infrastructure has any flaws that would later limit Phoenix's ability to use it. -- This is an automated message from the Apache Git Service.
