Hi there, I am evaluating several messaging platforms for using them in combination with a CEP engine. This targets developing a system for some kind of distributed CEP. I already have built a prototype doing some very basic analysis using Kafka & Esper.
Now I am wondering about runtime modification possibilities of this system: 1.) From what I've read and done so far, I suppose I can just add new calculations by registering new Consumers to new topics, is this correct? 2.) If so, how about updating existing calculations/applications? Will unregistering the old consumer and registering a new consumer to the same topic do the trick? 3.) Given questions 1&2 will be answered with yes, is there any way to prevent data loss while switching between versions? In case I just did not find the appropriate part of the documentation, just give me a hint/link. Any help will be appreciated. Regards, Benjamin
