Consistency Patterns (Strong, Eventual, Weak) in...

Understanding Consistency in Distributed Systems In distributed systems, consistency defines how and when updates to data become visible across multiple nodes or replicas. When a client performs a write operation on one node, the system must decide whether subsequent read operations on any other node will immediately reflect that change or tolerate some delay. This decision directly influences availability, latency, throughput, and overall system behavior under network partitions or failures. Co
