I am new to Siddhi CEP. We are planning to use it as a standalone java library. We planned to have one instance of SiddhiManager consuming different event streams with each event stream mapped to one execution plan with queries.
In the below mail thread there is mention to use one SiddhiManager instance per scenario.

So is there any limit on the number of execution plans per Siddhi Manager instance.
There is no limit like that where as you can have multiple ExecutionPlanRuntimes per SiddhiManager. Please use latest Siddhi 3.0.0 which was released last month and refer SiddhiQL 3.0.0 documentation for more details.
