What is the Raft algorithm and how does it work?

The Raft algorithm is a consensus algorithm designed to manage a replicated log. It ensures that multiple servers can agree on the same sequence of operations, even in the presence of failures.

What are the main components of the Raft algorithm?

The main components of the Raft algorithm include leader election, log replication, and safety mechanisms to ensure consistency.

How does leader election work in Raft?

In Raft, a leader is elected through a voting process. When a server becomes a candidate, it requests votes from other servers. The first to receive a majority of votes becomes the leader.

What happens if the leader fails?

If the leader fails, the remaining servers will initiate a new election to choose a new leader, ensuring that the system can continue to operate.

Can you explain log replication in more detail?

Sure! Log replication in Raft involves the leader sending log entries to follower servers. Followers append these entries to their logs and acknowledge receipt, ensuring all servers maintain the same log.
