How does the Replication Lag Calculator work?

Measure write to replica sync time Then: Calculate data loss window Then: Monitor for anomalies.

Can you give an example of how to use the Replication Lag Calculator?

Example: Input Master writes, replica 500ms behind gives a result of 500ms max data loss (RTO consideration).

Is the Replication Lag Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
