    Description

      The sync source reevaluation logic checks to see if any other sync source candidates are more than 30 seconds ahead of the current sync source. It uses heartbeat data to determine this, which means if no writes happen for longer than 30 seconds and then one write comes in, the different heartbeat timings may trigger the reevaluation unnecessarily.
