Hi Mark, Thanks. Some work has been done by Thomas Dudziak on integrating storm with esper [1][2].
What esper offers is: a. queries (select average(price) from events where type=buy) b. windows (the above for a window of 30 minutes) c. patterns (if event a is not followed within 5 minutes by event b) d. the dsl (everything can be done in sql-like query) So it can probably be built in storm, but it's not as easy to use. And since I don't need storm's distributed nature it could probably even be done in raw clojure.
