A database replication lag calculator estimates the delay between a write on a primary database and its appearance on replicas, based on write rate and replica throughput. High replication lag can cause stale reads and data inconsistencies in distributed systems.

Trin-for-trin guide

  1. 1Measure write to replica sync time
  2. 2Calculate data loss window
  3. 3Monitor for anomalies

Løste eksempler

Input
Master writes, replica 500ms behind
Resultat
500ms max data loss
RTO consideration
