Description: Session consistency is a fundamental concept in distributed databases. It refers to the guarantee that all reads and writes performed within the same session are consistent. This means that if a client performs a write and then reads the same data within the same session, they will retrieve the value they just wrote, regardless of replication state or network latency. This property is crucial for applications that require a high degree of transaction coherence, as it allows developers to build systems that behave predictably and reliably. Session consistency is achieved through the use of session identifiers and control mechanisms that ensure operations within that session are managed coherently. In a distributed environment, where multiple nodes may be involved in data handling, this consistency becomes a challenge, but it is essential for maintaining information integrity and user experience. In summary, session consistency is a key feature that enables distributed systems to provide reliable and predictable behavior in data management.
