What is eventual consistency in distributed databases?
- A consistency model where all nodes have the same data simultaneously
- A consistency model where data may be inconsistent temporarily
- A guarantee that updates propagate instantly across all nodes
- A state where data becomes consistent after a predetermined delay
Eventual consistency in distributed databases is a consistency model where data may be inconsistent temporarily but will eventually converge to a consistent state across all nodes without intervention. It allows for updates to propagate asynchronously, accommodating network partitions, latency, and concurrent modifications while maintaining system availability and performance. While eventual consistency prioritizes system responsiveness and fault tolerance, applications must handle potential inconsistencies during the convergence period.
