Raft Consensus Algorithm

The Raft Consensus Algorithm is a method used in distributed systems to ensure that multiple computers (or nodes) agree on a shared state, like a log of transactions. It works by electing a leader node that coordinates updates and ensures all nodes replicate the same information. If the leader fails, a new leader is elected. Raft helps maintain consistency and reliability, even if some nodes experience failures or network issues. This is crucial for systems where accurate data sharing is essential, such as databases or online transaction processes.
