Lag Time
Lag time measures the delay between when an update is made to a replica and when that update is propagated to all other replicas. Lower lag times indicate faster propagation of updates and better eventual consistency.
What is the Measurement of Eventual Consistency?
The measurement of Eventual Consistency in distributed systems typically involves assessing how quickly updates made to the system are propagated to all replicas and how long it takes for all replicas to converge to a consistent state. Several metrics can be used to measure eventual consistency:
