Subscribe to Events from the Event Bus or Apama
Events from other Software AG applications, such as Optimize and Apama, can be used as mashable information sources. You connect Prestoto the Event Bus or directly Apama, in some cases, and subscribe to a specific type of event or scenario. This subscription creates an event mashable in Presto.
Presto administrators create the connections and subscriptions for event mashables.
With Apama events, Presto can directly accesses event data in two ways:
Scenarios in
Apama have event data that has been transformed specifically for use in dashboards. (This is also sometimes called
dataviews.)
Presto works with Apama scenario events through the Event Service and event sources defined by a Presto administrator.
Distributed Stores in the
Apama MemoryStore hold data that can be shared across several correlators and monitors and can be used in dashboards. In some cases, this may be a very large dataset.
Data from these distributed Apama stores cannot be accessed as scenarios or as events. If the Apama MemoryStore uses BigMemory, however, Presto mashups can access this data using Presto Analytics and dynamic external stores. See
