I'm certainly not a grok expert and probably using it in simplest cases,
but in all the log ingestion use cases I'm working on, I'm usually fine with
the default patterns file (already loaded from classpath with the
processor/reader CS) and a few additional patterns for the log sources I'm
dealing with.
I'm not sure to see why composite groks would be an issue here? (I updated
the unit test to use one)
Do you have an example in mind? (again not a Grok expert :))
