Thank you, I didn't know it. I have been looking for some benchmarks joni vs java (defauld package), do you know some web with results? Anyway, I'll try for myself tomorrow.

Regex processing is not that slow - when adopting best practices. This project provides better performance compared to that of Java's: https://github.com/jruby/joni Cheers On Sun, Oct 5, 2014 at 1:18 PM, Guillermo Ortiz < gor...@pragsis.com > wrote: I thought something like that,, but I guess it should be a little more complex because it should look for a pattern, maybe a date format? An idea it's if you know that the first 10 digits are the date, you could get them and try to match with a date format or something more generic like a RE, although it seems too expensive in time process and the operations in the InputFormat should be pretty fast. Any better idea?

The problem that I have it's that if I have to read an Tomcat log for example, sometimes the exceptions are typed on several lines, but they should be processed just like one line, I mean all the lines together to the map. Is there something like that implemented? I've been looking for, but I don't find anything and I don't want to reinvent the wheel.
