Daily Term: Eventual Consistency

Eventual Consistency

Eventual Consistency is a model in distributed systems where, given enough time without further updates, all replicas of data will converge to the same state. For example, in a distributed database like DynamoDB, a write to one node might not immediately be visible to all nodes, but eventually, all nodes will reflect the update. This model prioritizes availability and partition tolerance but can lead to temporary inconsistencies in reads.
