Reference documentation and code samples for the Cloud Spanner V1 Client class DirectedReadOptions.
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.

Optional. Data for populating the Message object.
↳ include_replicas
DirectedReadOptions\IncludeReplicas
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.
↳ exclude_replicas
DirectedReadOptions\ExcludeReplicas
Exclude_replicas
indicates that specified replicas should be excluded from serving requests. Spanner doesn't route requests to the replicas in this list.
