Konstantin Osipov

13 minutesFebruary 9, 2022

ScyllaDB adopted Raft as a consensus protocol in order to dramatically improve our operational aspects as well as provide strong consistency to the end user. This talk will explain how Raft behaves in ScyllaDB Open Source 5.0, and introduces the first end-user visible major improvement: schema changes. Learn how cluster configuration resides in Raft, providing consistent cluster assembly and configuration management. This makes bootstrapping safer and provides reliable disaster recovery when you lose the majority of the cluster.
