How to configure the wait for sync value in Autofailover for a MySQL cluster in Scalearc.
Wait for sync is the time period in which the SB server should wait to get promoted as new Master till its replication lag with new slave is zero
for achieving a full sync. The default time period for performing such operation is configured via Failure timeout and Retry attempts as seen below:
The value of this time period is decided by two parameters:
a. Retry attempts - default 3
b. Retry interval - 1 sec.
Hence if the promotion of new master does not take place in 3 seconds then the operation is aborted. The time period of 3 seconds can be changed by
tuning values of Retry attempts and/or the value of Retry interval.
