GoogleApi.Spanner.V1.Model.DirectedReadOptions (google_api_spanner v0.48.0)

View Source

The DirectedReadOptions can be used to indicate which replicas or regions should be used for non-transactional reads or queries. DirectedReadOptions can only be specified for a read-only transaction, otherwise the API returns an INVALID_ARGUMENT error.

Attributes

  • excludeReplicas (type: GoogleApi.Spanner.V1.Model.ExcludeReplicas.t, default: nil) - Exclude_replicas indicates that specified replicas should be excluded from serving requests. Spanner doesn't route requests to the replicas in this list.
  • includeReplicas (type: GoogleApi.Spanner.V1.Model.IncludeReplicas.t, default: nil) - Include_replicas indicates the order of replicas (as they appear in this list) to process the request. If auto_failover_disabled is set to true and all replicas are exhausted without finding a healthy replica, Spanner waits for a replica in the list to become available, requests might fail due to DEADLINE_EXCEEDED errors.
