Comparison of a correlator and a context
Contexts allow EPL applications to organize work into threads that the correlator can execute concurrently.
In EPL, context is a reference type. When you create a variable of type context, or an event field of type context, you are actually creating an object that refers to a context. The context might or might not already exist. You can then use the context reference to spawn to the context or send an event to the context. When you spawn to a context, the correlator creates the context if it does not already exist.
