Constants
FAILOVER_MODE_UNSPECIFIED
Value: 0
Invalid value.
Generated from protobuf enum FAILOVER_MODE_UNSPECIFIED = 0;
SOFT
Value: 1
When customers initiate a soft failover, BigQuery will wait until all committed writes are replicated to the secondary. This mode requires both regions to be available for the failover to succeed and prevents data loss.
Generated from protobuf enum SOFT = 1;
HARD
Value: 2
When customers initiate a hard failover, BigQuery will not wait until all committed writes are replicated to the secondary. There can be data loss for hard failover.
Generated from protobuf enum HARD = 2;
