What are the advantages of WANdiscos quorum based approach?
Ans. The first advantage is that WANdisco’s quorum approach increases availability by ensuring that transactions can still be committed as long as a quorum of the development sites are up. The second advantage is that it ensures that repositories do not go out of sync even when the network partitions. WANdisco also employs the concept of a distinguished node, or singleton quorum. For scenarios where there is an even number of WANdisco development sites (nodes), the distinguished node can act as a tie-breaker, so that transactions can still be committed. WANdisco builds on the quorum concept to provide a follow-the-sun capability that allows performance to be enhanced for each site’s normal working hours.
