Read-Your-Writes

← Back to Consistency Models

A client always sees its own writes in subsequent reads, even if other clients may see stale data. A practical guarantee that prevents the confusing experience of submitting a form and not seeing your change. Can be implemented by routing reads to the same replica that accepted the write or tracking write timestamps.
