streamsql.org blogs

blogs.streamsql.org is a new multi-author blog about interesting topics in stream processing. It's hosted by StreamBase, and the main authors are probably going to be university professors and/or developers associated with StreamBase. I think it would be great if we could get posts by people from Coral8 and Apama too. So far there are posts by Mitch Cherniack (from Brandeis) and Ugur Cetintemel (from Brown).

I'll probably write a few posts for that site over the next few months. Topics I'm considering writing about:

• The difference between events (i.e. change notification messages) versus behaviors (variables whose value changes continually). Why I argued against the "inserts" stream.
• Syntactic and semantic drawbacks to basing a language on SQL. What StreamSQL might look like if it had combinators, and what the consequences would be for optimization.
• Static schemas versus dynamic schemas (self-describing data).
• Why StreamSQL needs compound data types, even though relational SQL doesn't.
