Yes there is a better implementation. Defining the same context multiple times may actually impact performance. Esper 8 is a compiler and a runtime, while Esper 7 and older was just a runtime with an interpreter. The Esper 8 compiler has a path which tells it what existing contexts, named windows, event types etc. there are. One of the other grapes some users had with old versions of Esper was that there was no real multitenancy as everything was visible to everything. Esper 8 fixed that with access modifiers.
For reading up, there are some posts for migrating applications from older versions. The link is (https://www.espertech.com/2018/10/23/esper-8-migrating-step-by-step-for-existing-applications/) and documentation link is compiler arguments
from esper.
