Great looking release. I’m really excited to see if the cstore extension can make good use of the parallelism improvements.

- macdice 8y agoIt looks like someone would need to do the things described in here: https://www.postgresql.org/message-id/flat/CA%2Bz6ocRFEnThhXye3F9_ZjSMDSfOGdnGOt8hnXsVgGmFpNTYFA%40mail.gmail.com https://www.postgresql.org/message-id/flat/CA%2Bz6ocRFEnThhX... There is an easy level "parallel safe" that would allow scans of different cstore partitions in a parallel query, and a harder-to-code "parallel aware" level that would allow parallel scans on one individual cstore_fdw relation. AFAIK no FDW has attempted parallel scans yet, but cstore looks like it may be an ideal case to be first?
