Reference documentation and code samples for the Google Cloud Spanner v1 API class DirectedReadOptions.Types.ReplicaSelection.
The directed read replica selector.
Callers must provide one or more of the following fields for replica
selection:
location - The location must be one of the regions within the
multi-region configuration of your database.
type - The type of the replica.
Some examples of using replica_selectors are:
location:us-east1 --> The "us-east1" replica(s) of any available type
will be used to process the request.
type:READ_ONLY --> The "READ_ONLY" type replica(s) in nearest
available location will be used to process the
request.
location:us-east1 type:READ_ONLY --> The "READ_ONLY" type replica(s)
in location "us-east1" will be used to process
the request.
