terrytlu updated HBASE-28860:
-----------------------------
Description:
Add a metric of the amount of data written to WAL to determine the pressure of
replication.
Combined with the replication shipped size metric, the user can determine how
many RegionServers are needed to meet the data(WAL) writing requirements, that
is to achieve the goal of no replication lag.
In the postAppend method of ReplicationSourceWALActionListener, the amount of
WAL data that needs to be replicated is counted, and the filter logic in
replication is reused.
Alos add a hbase.replication.walAppendsize.metric.enable=false config to
disable this metric, if it has some side effect.
