One of the most critical aspects of data replication performance is latency. The two most important types are replication latency and application latency. Replication latency is the time period when the change data is in the replication pipeline and is affected by system utilization, process priorities, and network bandwidth.
Application latency occurs when the source application calls transaction commit to make its data changes permanent. Shadowbase Zero Data Loss must ensure that the data changes are safe-stored on the target system before allowing the source transaction to commit. A consequence of this process is that the time taken for the source application’s transaction commit to complete may be extended.
