quorum-based replication

Quorum-based replication is a method used to ensure data consistency across multiple servers. Imagine a group where decisions are only made if more than half of members agree. Similarly, in this system, a written or read operation is considered successful only when a majority of servers acknowledge it. This approach prevents conflicts or data loss, even if some servers fail. It balances availability and reliability by ensuring data remains accurate and up-to-date, making distributed systems more robust and resilient to failures.
