resource_broker_config

The resource broker is an actor service that controls resource consumption on YDB nodes, such as:

CPU — number of threads
Memory — RAM

Different types of activities (background operations, TTL data deletion, etc.) run in different resource broker queues. Each queue has a limited number of resources:

Queue name	CPU	Memory	Description
`queue_ttl`	2	—	TTL data deletion operations.
`queue_backup`	2	—	Backup operations.
`queue_restore`	2	—	Restore from backup operations.
`queue_build_index`	10	—	Online secondary index creation operations.
`queue_cdc_initial_scan`	4	—	Initial table scan operations.

Note

It is recommended to extend the resource broker configuration using tags !inherit and !append.

Example of extending the resource broker configuration with a custom limit for the queue_ttl queue:

resource_broker_config: !inherit
  queues: !append
  - name: queue_ttl
    limit:
      cpu: 4
