Citus Blog

If you're looking at Citus its likely you've outgrown a single node database. In most cases your application is no longer performing as you’d like. In cases where your data is still under 100 GB a single Postgres instance will still work well for you, and is a great choice. At levels beyond that Citus can help, but how you model your data has a major impact on how much performance you're able to get out of the system.
