StreamCruncher 1.09 Beta is ready and it includes a major feature addition. From version 1.09 onwards, Multi-Stream Correlation a.k.a Pattern matching is possible. This feature enables the monitoring of and correlation across multiple Streams of Events using a simple SQL-like Query.

Although simple 2 Stream Correlation is possible using regular SQL plus Partitions, as demonstrated in the SLAAlertTest, watching for multiple Patterns across more than 2 Streams is now very easy with this new "alert..using..when.." clause.

MultiStreamEventGeneratorChainTest demonstrates this new feature.
