Query Agents
Query agents use an SQL-like query language. You can query data that is in the cache. You can also query data arriving in events, known as event stream processing or ESP.
A query agent is a non-reasoning agent. It has read-only access to the underlying objects in the cache cluster. A query agent can execute rule functions, but not rules. You can mix query agents and inference agents within one node as desired.
