A couple thoughts: - With Redshift, you can just click a couple buttons in the AWS console to create a new DB and try it out. When you're done experimenting, you can shut it off. - Citus is open source, so you can experiment on your own hardware. - If you already have data as CSVs in an S3 bucket, it's a couple SQL commands to load it into Redshift. I don't see as nice an import option for Citus. - Citus is designed to support mixing operational and analytic workloads. Redshift is just for analytics. - Citus Cloud plans start at $1,800/month. Redshift clusters can be made a lot cheaper by snapshotting and spinning them down when not in use.
