The MemoryStore provides an in-memory, table-based, data storage abstraction within a correlator. All EPL code running in a correlator in any context can access the data stored by the MemoryStore. In other words, all EPL monitors running in a correlator have access to the same data. The Apama MemoryStore can also be used in a distributed fashion to provide access to data stored in a MemoryStore to applications running in a cluster of multiple correlators.
