An introduction to Raft

An introduction to Raft

Let's investigate why the Raft algorithm was created when there was already a Paxos algorithm for solving the consensus problem.

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 ...
