An introduction to Raft
Explore the Raft consensus algorithm to understand how distributed systems achieve agreement through leader election, node states, and term-based voting. Learn how Raft manages replicated logs and prevents split leadership for robust system coordination.
We'll cover the following...
Motivation
Paxos has been the canonical solution to the consensus problem. However, the initial specification of the algorithm did not cover some aspects that were crucial in implementing the algorithm in practice, some of these aspects were covered in subsequent papers.
The Paxos algorithm is also widely considered hard to understand.
As a response to these issues, researchers decided to create a new algorithm with the goals of improved understandability and ease of implementation. This algorithm, proposed by ...
