Indicates the quorum type of this instance configuration.
Constants
QUORUM_TYPE_UNSPECIFIED
value: 0 Quorum type not specified.
REGION
value: 1 An instance configuration tagged with REGION quorum type forms a write
quorum in a single region.
DUAL_REGION
value: 2 An instance configuration tagged with the DUAL_REGION quorum type forms
a write quorum with exactly two read-write regions in a multi-region
configuration.
This instance configuration requires failover in the event of
regional failures.
MULTI_REGION
value: 3 An instance configuration tagged with the MULTI_REGION quorum type
forms a write quorum from replicas that are spread across more than one
region in a multi-region configuration.
