When the user sets the MinimizeSkew flag we is within 1 second of each other. To account for rounding-off of the transaction timestamp and the clock-skew we set the threshold to be 2 seconds, instead of 1 second, so that we don’t keep stalling the source vttablet sends its current time along with every event. This allows the target to correct for clock skew while estimating replication lag. Additionally, the source starts sending heartbeats if there

This allows the target to correct for clock skew while estimating replication lag. Additionally, the source starts sending heartbeats if there are: – Each migration requires a failover (aka successover, aka planned reparent). – Total wall clock time is higher since we run the same migration in sequence on different servers.
