Maarten Breddels commented on ARROW-555:
----------------------------------------

Related: https://issues.apache.org/jira/browse/ARROW-7083

I will probably start working on this a few weeks from now. My initial 
intention would be to separate the algorithms as much as possible so it would 
be possible to add them both to gandiva and a 'bare' kernel, or with a minimal 
amount of refactoring.

[~wesm]: what's your reason to choose re2? Gandiva and vaex both use pcre, but 
I have no strong preference (except being a bit familiar with pcre).
