I haven't read all your docs exhaustively, but how do you solve joining your parallelized query results without running into spill problems? Or rather, how do you solve for spill? Once your hypertables balloon to large sizes, you may be able to store handily across many Postgres instances, but collating the sub-queries will be costly. Spilling to e.g. S3 is a potential solution, but brings with it a new bag of problems, not to mention cost.
