Raft algorithm

The Raft algorithm is a method used by computers to work together and stay synchronized, ensuring everyone agrees on the same information. Imagine a group of friends keeping a shared notebook; Raft helps elect a leader who writes updates, like new diary entries, so everyone sees the same pages in the same order. If the leader fails, the group quickly votes to pick a new one, maintaining consistency. This process ensures reliable coordination even when some members or computers experience issues, making distributed systems like databases resilient and effective.
