I've never even heard of SciDB, thanks for the pointer. I have heard of VoltDB and the only thing I remembered was that it was in-memory... I'm still not 100% sure what SciDB is for but it looks like none of the databases we're mentioning are directly comparable: - SciDB for scientific computing (??) - VoltDB for in memory + SQL - Druid for OLAP queries - TimescaleDB for row-based timeseries storage Seems like all apples to oranges to me. I personally like TimescaleDB because it runs on Postgres and I can usually find a way to do all those other things in postgres relatively efficiently (memory requires some squinting while using UNLOGGED tables).
