Is it to improve query performance on analytics dbs? I do know there are many older schemas for Growth-related experiments that are only really useful for historical analysis, which is kind of hard to reconstruct anyway. If there are sound technical reasons to chuck stuff from the relational dbs and retain it only in the raw JSON logs, then I'm potentially okay with helping figure out a list of schemas to retain and schemas to purge.
