Context:
in Wso2, to make Siddhi apps dynamic, one uses business rules.
This business rules are created from templates like this:
Rule templates have some properties for each attribute. In this properties there are options to make a list of possible values for attributes. What I wonder is how to make these options dynamic, like calling from an external API or from the DB.
We are not supporting this feature for now in Stream Processor. You can request this feature by opening an issue in WSO2 GitHub repository.
