Automatic Repair¶

Traditionally, launching repairs in a ScyllaDB cluster is left to an external process, typically done via Scylla Manager.

Automatic repair offers built-in scheduling in ScyllaDB itself. If the time since the last repair is greater than the configured repair interval, ScyllaDB will start a repair for the tablet tablet automatically. Repairs are spread over time and among nodes and shards, to avoid load spikes or any adverse effects on user workloads.

To enable automatic repair, add this to the configuration (scylla.yaml):

auto_repair_enabled_default: true
auto_repair_threshold_default_in_seconds: 86400

This will enable automatic repair for all tables with a repair period of 1 day. This configuration has to be set on each node, to an identical value. More featureful configuration methods will be implemented in the future.

To disable, set auto_repair_enabled_default: false.

Automatic repair relies on Incremental Repair and as such it only works with tablet tables.
