I'm pleased to announce the initial availability (1.0 Beta) of StreamCruncher -, a lightweight Event Processing Kernel.

It's a multi-threaded Java program that provides an extention to the SQL language with Event processing constructs. It supports Sliding Windows, Time based Windows, Partitions and Aggregates. It also provides a feature similar to Materialized Views. Joins and Sub- queries are also supported to allow Event Co-relation.

StreamCruncher requires a Database underneath, to do the heavy-lifting. Several Databases (5 DBs) are supported. In-Memory Databases like - MySQL with Memory/Heap Engine, Oracle TimesTen and H2 are favored. It also supports Derby and Firebird, although with slight modifications to the Page Cache and Disk Flush settings etc to make them run faster.

It is Free, with a commercial-friendly License.

I hope you'll give it a shot. I'd love to hear your feedback. full year. Weekends, weekdays, late nights, holidays - oh man! Why would anyone do it? Well, why do people spend hours and hours at the Gym, sculpting their bodies? Back breaking work, but the sense of accomplishment you get at the end of it is something one can only understand if one goes through it, first hand.
