TSSJS: Event Processing In Java

I’ve always thought that Esper is a great project, and being in the SOA/ESB space Esper has a lot of applicability for the systems our company works on. Thomas did his best to describe what you can do with Esper, but it’s pretty tricky to describe useful Esper queries effectively in PowerPoint slide. The kind of stuff you can do with Esper is awesome and Thomas Bernhardt has done a great job on this project.
I think the sentence that summed up what it’s like working with Esper was -
“it’s like performing time-aware SQL queries.”
Basically, you can define section criteria (query) on multiple event streams (tables) within time “windows” and perform joins to create associations between event streams.
