Database Replication Explained (in 5 Minutes)

Make sure you're interview-ready with Exponent's system design interview prep course: https://bit.ly/47frhp3

In this video, we discuss database replication. This involves copying data to multiple sources to prevent data loss and improve system performance. Different strategies exist, like leader-follower, multi-leader, and leaderless replication, each with their own trade-offs.

Synchronous replication ensures data consistency but can be slow, while asynchronous replication sacrifices consistency for speed. Multi-leader replication mitigates leader failures, but complexity increases.

Leaderless replication eliminates the leader-follower hierarchy but requires managing read and write capable replicas. Including replicas is generally recommended for distributed systems, and the choice of strategy depends on your specific needs.
