Adam Bosworth on Event Systems at HPTS
Adam described 4 styles of event /
pub&sub systems that he thinks will emerge, each with different scalability
characteristics
- Enterprise Application Integration. The average enterprise has
about 5000 applications that are one by one integrated into becoming event
generators for the EAI portals. Important here is that the data model needs
to be flexible as you do not know what apps will need be integrated
tomorrow. Medium number of publishers, medium number of subscribers.
- Business to Business. A limited number of customers (up to a
thousand), and at most 2-4 applications that are receiving the inbound events.
Transaction rates are low.
- Mobile. The mobile operators want to start using your locality
information to start providing targeted information to you in a style
similar to advertisements in Minority Report. You get to subscribe to
'send me an sms with Gap's items on sales when I enter the xyz mall'.
Lots of temporal events with location information, and potentially many
subscribers
- RFID. The volume of this stuff is going to be unbelievable, but many of the event may be discarded given that there is no change in location
