Hi guys, I read the article [1] that details a performance test conducted on CEP integration on Storm. I have some questions regarding how this integration actually work and how this fits in with the DAS picture.
1) In the article it says that siddhi runs inside storm. Does this mean that we have converted siddhi engine to a bolt to run inside the storm environment? 2) How is the CEP query broken down into bolts and spouts? In the documentation its states we have a bunch of annotations to set bolts and spouts for the plan. For example:- do we need to change the way we do a window count? Like create streams separately for the spouts or is this handled by CEP manager? 3) What's the exact difference of Siddhi and Storm? I feel like both have the same concepts. 4) In a DAS Deployment - does this mean that the event receiver node is going to communicate with storm for processing? Will this incur a significant performance hit on the event receiver?
