Eventual consistency is a consistency model used in distributed systems to ensure that, given enough time without new updates, all replicas of the data will converge to the same state. It allows for temporary inconsistencies, prioritizing availability and partition tolerance over immediate consistency, which is particularly useful in highly distributed environments.

Eventual consistency

A consistency model defines the rules and guarantees concerning the visibility and order of updates in a distributed system, impacting how data is read and written across nodes. It balances trade-offs between performance, availability, and correctness, influencing system design and user experience.

Distributed systems consist of multiple interconnected components that communicate and coordinate their actions by passing messages to achieve a common goal. They offer scalability, fault tolerance, and resource sharing, but also introduce challenges such as network latency, data consistency, and system complexity.

Availability refers to the degree to which a system, service, or resource is operational and accessible when required for use. It is a critical aspect of system design and management, ensuring that users can rely on consistent performance and minimal downtime.

availability

Partition tolerance is a property of distributed systems that ensures the system continues to operate despite network partitions, where some nodes cannot communicate with others. This means that the system can sustain a loss of connectivity between nodes and still provide some level of service, though potentially with reduced consistency or availability.
