Description: Quorum write is a fundamental concept in distributed database systems. It refers to a write operation that requires a quorum of replicas to acknowledge the write for it to be considered successful. In simple terms, a quorum is defined as more than half of the replicas that store the data. This approach ensures that the written information is consistent and available, even in situations where some replicas may fail or be disconnected. Quorum write is crucial for maintaining data integrity in distributed environments, where latency and availability are critical factors. By requiring a minimum number of replicas to confirm the write, the risk of inconsistent reads or stale data is minimized. This technique is part of a broader approach known as eventual consistency, which seeks to balance availability and consistency in distributed systems. In summary, quorum write is a strategy that allows distributed databases to operate efficiently and reliably, ensuring that write operations are acknowledged by a sufficient number of nodes before being considered successful.
