Esper does exactly this - you run streams of events over it and it continuously executes SQL to see if it matches. If so you can:
- run code
- make new streams
- store the results
Esper's been doing this kind of thing for 9 years now.
- ak4g 11y agoEsper is really curious. I looked at it while getting a feel for the general landscape of streaming data tools in late 2013 - to be clear, it was a very cursory look, on the timescale of a few hours at most. I quote what my final take-away was at the time: > Seems good but... such a weird project. Codehaus, svn, not high activity, but consistent, stable releases for five years. Maybe just not the kind of thing webdevs get into? Not sure if that's a strike against or not. With the demise of Codehaus it looks like they've moved to github: https://github.com/espertechinc/esper https://github.com/espertechinc/esper But oddly they don't seem to have migrated their svn history, and the README implies they don't plan to... I certainly hope they didn't lose it when Codehaus shut down. There was, as noted, already 9 years worth of code changes in that repo. That would be unfortunate.
