Często zadawane pytania

When should I estimate replication lag?
For a chain model (segment × hops) and comparison against RPO.
What does high lag mean?
The replica is behind — reads may be stale; RPO risk.
What values are realistic?
Sync: ms to tens of ms; async: hundreds of ms to seconds under load.
What looks “bad”?
Lag above RPO or a rising trend — scale or change sync strategy.
