-----------------------------------
And I also executed a 1000000 rows test for HBASE-26233 branch
The command is
{noformat}
./bin/hbase org.apache.hadoop.hbase.RegionReplicationLagEvaluation -vlen 1024
-r 1000000
{noformat}
The result are

During the test, the region is split, and is also flushed several times. But
the 99.9% lag is still same, and the max lag is only 335 ms.
