What is WANdiscos follow-the-sun option?

Ans. This option allows the distinguished node or quorum to be configured to rotate to another site or group of sites to optimize performance during their normal working hours. For example, if a server in Bangalore, India needs to be kept in sync with a server in San Jose, California, WANdisco can be configured so that during each site’s normal working hours, that site can become the distinguished node, and write steps incur no WAN latency. During Bangalore’s normal workday, updates are still propagated to San Jose; however they now occur in the background asynchronously. After the workday ends in Bangalore, the distinguished node will rotate to the San Jose site, and San Jose’s writes will incur no WAN latency, as changes from San Jose are then propagated asynchronously to Bangalore.
