How many rows are we talking about? In the end once I started using dblink to load via redshift after some preprocessing the loads were reasonable, and indexing too. But I’m looking at full data refreshes every two weeks and a tight budget (30 bucks a month) so am constrained on solutions. Suggestions welcome!
