Abstract: A device can receive a plurality of input event objects that correspond to publications in a publication-subscription deployment, where the plurality of input event objects are associated with respective originating accounts and respective originating signatures. The device can identify, using a query, a set of input event objects, of the plurality of input event objects, based on which of one or more operations are to be invoked, where the query is based on the respective originating accounts and the respective originating signatures, and where the query returns respective output signatures corresponding to the set of input event objects. The device can generate one or more output event objects that include or identify the respective output signatures corresponding to the set of input event objects, and provide, to an event bus, the one or more output event objects to cause the one or more operations to be invoked.
