Basic Repair Service configuration reference

Reference of basic options without defaults that can be configured by all customers for their unique environment, such as which tables to include in incremental repairs or which keyspaces or tables to exclude from subrange repairs.

This reference contains the basic Repair Service options without defaults that can be configured by all customers for their unique environment, such as which tables to include in incremental repairs, or which keyspaces or tables to exclude from subrange repairs. Subrange repairs exclude certain system keyspaces and tables by default. Incremental repairs include certain OpsCenter tables by default. Any tables being repaired incrementally are not subjected to subrange repairs.

The following options are currently configurable by adding a [repair_service] section to the opscenterd.conf file to apply to all clusters, or per cluster by adding the section to the cluster_name.conf file. Settings in cluster_name.conf override any settings in opscenterd.conf. After changing configuration, restart opscenterd.

If there are any issues with the Repair Service configuration, the Repair service not configured correctly rule in the Best Practice Service fails and provides guidance as to incorrectly configured options, unless the rule has been turned off.

Repair Service Best Practice Rules

Basic configuration for subrange repairs

Flag which keyspaces or tables therein to exclude from subrange repairs:

[repair_service] ignore_keyspaces: The list of keyspaces to ignore during a subrange or distributed subrange repair, in addition to system keyspaces or those with a replication factor of 1.
[repair_service] ignore_tables: The list of keyspace-qualified table names to exclude during a subrange or distributed subrange repair, including reserved tables, those that reside in a system keyspace, and tables belonging to keyspaces with a replication factor of 1. Example: keyspace1.standard1, keyspace1.standard2.

Basic configuration for incremental repairs

Flag which tables or datacenters to include in incremental repairs:

[repair_service] incremental_repair_datacenters: Restricts incremental repairs by datacenters or racks. Setting this option improves performance by limiting the repair requests to only those replicas within the datacenters and any specified racks. Example: dc1,dc2:rack1,dc2:rack2. The default behavior sends repair requests to all datacenters and racks for all replicas.
[repair_service] incremental_repair_tables: The list of keyspaces and tables to include in incremental repairs. The OpsCenter.settings and OpsCenter.backup_reports tables are included by default. Example: keyspace1.standard1, keyspace1.standard2.

Note: The OpsCenter.settings and OpsCenter.backup_reports tables are included in incremental repairs by default.
