Last week was the ACM / Eurosys / CANOE “Events, Publish/Subscribe, and Systems” International Summer School, held in Norway near Oslo, and TIBCO contributed some thoughts on “Commercial Trends in Event Processing” as well as the Panel on “Streams vs Rules vs Subscriptions”.
Most of the audience were European PhD students, and I have to say there is quite a lot of interesting research going on. Some of the TIBCO academic research suggestions were well received or already in progress.
The organisers did a good job in getting some good speakers from the commercial world too:
- John Reumann from Google gave some good insight into a commercial (if specialist) pub-sub software creation project, presenting things like:
- a decision tree for communication patterns versus technology selections,
- how de-duping was a difficult task in event streams, and
- how their “service monitor” had ~100 alert rules as well as doing regular probes of running systems to check on their health.
- Bugra Gedik from IBM presented on their InfoSpheres / System S stream processing project and associated language, which is interesting because it is about sequencing streams of events across parallel hardware systems with specialist operations including split and join.
- Angelo Corsaro from Prismtech presented on the OMG DDS pub-sub standard and how DDS has now gone open source.
- Guy Corland from Gigaspaces presented on their Java Spaces solution which is now apparently a distributed event-aware app server – indeed this pitch seemed very familiar as “Event Based Application Platform” is also a role played by TIBCO BusinessEvents with its own distributed event store (albeit using a different technology than Gigaspaces) and additional query and rule engine elements. And apparently Gigaspaces hasn’t been acquired by VMWare yet, even though Guy emphasized the role of spring containers …
Overall it was an interesting event and benefited over DEBS (IMHO) by mixing academic research posters with commercial updates.
