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.

it was awesome to hear a product manger explain this, I worked on this with my team for 2 years and not a single dev i worked with could explain this to me in layman's terms
I still can't believe you explained it so well in 5 minutes! Thanks
You make system design feel so easy
Excellent presentation and clear explanation. Very useful for understanding the database replication.
I find the grokking the system design interview book really helpful too it makes it so smooth to learn.
this is a great topic. if u can xpand on this itll be great. lot of q asked now in this domain
that was super helpful, thanks
where is the link you mentioned in the video for detail learning of selecting the best strategies for DB replica
Nice👍
Hi, could you please share how do you guys make this database image ?
We design in Figma and then animate using Adobe After Effects. Then edit in Davinci Resolve!
Once Report Manager Started, then replication is initialised.
