appliedLatency is the latency between
the commit time of the source event and the time the last
committed transaction reached the end of the corresponding
pipeline within the replicator.
Within a master, this indicates the latency between the
transaction commit time and when it was written to the THL. In a
slave, it indicates the latency between the commit time on the
master database and when the transaction has been committed to
the destination database. Clocks must be synchronized across
hosts for this information to be accurate.
appliedLatency : 0.828
The latency is measure in seconds. Increasing latency may
indicate that the destination database is unable to keep up with
the transactions from the master.
In replicators that are operating with parallel apply,
appliedLatency indicates the latency of
the trailing channel. Because the parallel apply mechanism does
not update all channels simultaneously, the figure shown may
trail significantly from the actual latency.
