🔴 How DataBase Replication works? WATCH THIS before your System Design Interview

In this video, we understand what is Distributed Data, its benefits and how does Replication work behind the scenes. How is Replication Sync happening, what are the possible architectures, what are their benefits and drawbacks? The DDIA Book is a great recommendation for System Design and I would like to summarise the chapters and my learnings here.
