SQL Interview Questions and Answers: Replication (Sync & Async)

In this sql interview questions and answers video we'll help you get ready for one of the sql interview questions asked in regards to database replication and tell you the difference between synchronous sql database replication and asynchronous sql database replication.

The eprimary difference between the two types of database replication is the way data is written to the servers.
When data is written to the primary and replica sql servers simultaneously, we have synchronous database replication.
When data is written to primary storage and after that - to the replica server, we have asynchronous database replication.
With synchronous sql database replication, data to both database servers will be written simultaneously.
With asynchronous sql database replication, the origin database server won't wait for confirmation from the destination database server.
