ScyllaDB Streaming and Repair Updates

Streaming is an internal operation that moves data from node to node over a network. It is the foundation of various ScyllaDB cluster operations, e.g., add node, decommission node and rebuild node. Repair is another important operation that detects the mismatch between multiple replicas on different nodes and synchronizes the replicas. In this talk, we cover recent changes and performance improvements to streaming and repair and introduce the new ScyllaDB streaming and the brand new row-level repair that will be released in the upcoming ScyllaDB releases.
