We've been running on Citus for about 2 months now, with a saas app that has lots of reporting functionality. It's no different than standard postgres in terms of configuration, other than that you have to define a distribution column for the tables you want to be distributed into tenants (e.g. accounts for saas). That's how you really see a significant benefit when working with larger datasets. That and the extra memory they provide over other managed postgres services. For us, "distributing our tables" meant just adding a rails migration using their gem. We were upgrading from heroku postgres, and chose this over RDS, because they take care of the distribution of data into tenants without us having to change our logic, since everything our users create was already getting associated to their organization / account. Only issue we've had was at one point we hit our plan's database connection limit of 300 for a few minutes, because of a new long running query we added, that started locking up connections and causing timeouts as soon as we went to production. We reached out immediately and their team jumped all over it to help us free up those connections, while we fixed the query.
