Consistency in State/Memory Manipulation – CC
Stronger consistency levels, such as strong consistency, ensure that data is immediately synchronized across all nodes, but this can introduce significant latency and reduce system performance, especially in geographically distributed systems. Weaker consistency levels, like eventual consistency, reduce synchronization overhead, improving performance at the cost of delayed consistency.
