However, we always considered Cassandra to be just a starting point.

SteelHouse: How Our Real-Time Switchover from Cassandra to Scylla Saved the Day

SteelHouse: How Our Real-Time Switchover from Cassandra to Scylla Saved the Day

Once we set up the first Scylla cluster, we realized that Scylla mostly tunes itself. That seemed like a pretty impressive feat, knowing that the system could be installed, auto-tune, and be ready for a production workload. We were heartened to know that the engineering team at Scylla had put a lot of effort into making sure their product will perform well out of the box.
