This lesson deals with what repair is and why it is needed. What are Tombstones, why it is important, and ScyllaDB Manager.
ScyllaDB Manager is a centralized cluster administration and recurrent tasks automation tool. ScyllaDB Manager can schedule tasks such as repairs and backups.
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. The best use of ScyllaDB repair is to have the ScyllaDB Manager schedule and run the repairs for you.
