The author of the text argues that consensus algorithms, which are currently widely used in distributed systems to ensure data durability, availability, and automation, may not be sufficient for future systems due to evolving problems such as complex topologies, pricing structures, and scalability. The author proposes building flexibility into these systems by specifying requirements and trade-offs, rather than relying on rigid algorithms like Paxos or Raft. This approach is being developed in the Vitess system, which allows users to define their own parameters without compromising performance. The author will take readers through a journey of dissecting consensus algorithms and building new rules and principles using more flexible algorithms.
