In this lesson you’ll learn about repair and why is it needed. A common misconception is that repairs are a way to fix “things” that are wrong with the database.
So what are repairs? ScyllaDB Repair is a process that runs in the background and synchronizes the data between nodes so that eventually, all the replicas hold the same data. Data stored on nodes can become inconsistent with other replicas over time, which is why repairs are a necessary part of database maintenance. Using ScyllaDB repair makes data on the node consistent with the other nodes in the cluster.
