Scylla Summit 2021

Many Scylla maintenance operations require significant data movement between database nodes in a cluster. It is not an easy task to make the management operations efficient while maintaining minimum impact on the workload all the time. In this talk, we will share how we made those maintenance operations easier, safer and faster with the new Scylla features and improvements, e.g., seedless, repair based node operations, smarter off-strategy compaction, io bandwidth limiter for repair and compaction, parallel repair in Scylla Manger and more.
