Automatic Repair
|
|
================
|
|
|
|
Traditionally, launching :doc:`repairs </operating-scylla/procedures/maintenance/repair>` in a ScyllaDB cluster is left to an external process, typically done via `Scylla Manager <https://manager.docs.scylladb.com/stable/repair/index.html>`_.
|
|
|
|
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 :doc:`tablet table </architecture/tablets>` 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``):
|
|
|
|
.. code-block:: 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 :doc:`Incremental Repair </features/incremental-repair>` and as such it only works with :doc:`tablet </architecture/tablets>` tables.
