Subject [jira] [Commented] (ACCUMULO-3191) Use JONI regex library to speed up operations
Date Wed, 01 Oct 2014 20:00:34 GMT


Christopher Tubbs commented on ACCUMULO-3191:

Should be careful if this new library changes existing behavior (different regex nuances,
features, etc.). It might be better served as an alternative iterator than one that replaces
the existing regex one.

I've also been thinking that we should probably create a sub-project/contrib library for iterators,
constraints, add-ons, etc. that are in user-land, for things like this, which might draw in
additional optional dependencies, but aren't really needed for the core project. (RegexIterator
is still needed in core, though, to support grep in the shell.)

> We could use the JONI library in things like the RegexIterator, because it's dealing
with byte arrays natively already. We should investigate the benefit and see if we can get
a speedup.
