How a record is updated on the replica?


I could not find an answer to this hence posting this question. Suppose my replication factor is 2(any X greater than 1), and i have configured my write to be acknowledged once all the replicas have been committed. So in this situation, is the record updated in parallel on both master and replica or the replica write starts only when master write is over?


It is a bit of both – the replica write is sent after the master has reserved space to write locally.
