Reference documentation and code samples for the BigQuery Reservation v1 API enum FailoverMode.
The failover mode when a user initiates a failover on a reservation
determines how writes that arepending replication are handled after the
failover is initiated.
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.
Soft
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.
