-  Session consistency is the widely used consistency level for both single region as well as globally distributed applications. It provides write latencies, availability, and read throughput comparable to that of eventual consistency but also provides the consistency guarantees that suit the needs of applications written to operate in the context of a user. The following graphic illustrates the session consistency with musical notes. The "West US 2" region and the "East US 2" regions are using the same session (Session A) so they both read the data at the same time. Whereas the "Australia East" region is using "Session B" so, it receives data later but in the same order as the writes.
