As long as you turn a PG table into a BQ dataset with enough partitions (BQ tables) such that queries do not touch a disproportionate amount of unnecessary data, you utilize date partitioning, and you can deal with a minimum 1.5 second query time the service is truly amazing. My only frustrations are that the majority of streaming service degradations are never noted on the Status dashboard and that you can get really odd error states like headers stating that you should be getting json while the body contains a html error message.
