What is Latency?   • SomeTImes refered to as “replicaTIon lag”   • The amount of TIme delay between an update applied in the   source database and the same update applied in the backup   target   • The shorter the duraTIon, the lower the latency   • High latency means the target is not up-to-date, but is not   an indication that there are any synchronization issues. The   target may still be accurately synchronized with what the   source was at some point in the (recent) past
