------------------------------------------------
Possible to extract
{code}
+ rowdone ++;
+ if (scanLimit > 0) {
+ long sleepTimeInMs = 1000 * rowdone / scanLimit -
(System.currentTimeMillis() - st);
+ if (sleepTimeInMs > 0) {
+ try {
+ Thread.sleep(sleepTimeInMs);
+ } catch (InterruptedException e) {
+ // do nothing.
+ }
+ }
+ }
{code}
This to a common method? Else looks good to me.

> Add option to limit the scan speed in CopyTable and VerifyReplication.
> When adding a new replication, we use 'CopyTable' to copy old data from
> online cluster to peer cluster. After that, we use 'VerifyReplication' to
> check the data consistency of two clusters.
> To reduce the impact the online cluster's service, we add an option to limit
> the scan speed.
