That's awesome, I've been itching to do that but never got around to it.. Garrit, do you have any benchmarks on read speeds?
I don't know about putting this in piggybank, as it carries with it pretty significant dependencies, increasing the size of the jar and making it difficult for users to don't need it to build piggybank in the first place. We might want to consider some other contrib for it -- maybe a "misc" contrib that would have indivudual ant targets for these kinds of compatibility submissions? -D On Mon, Nov 30, 2009 at 3:09 PM, Olga Natkovich <ol...@yahoo-inc.com> wrote: > Hi Garrit, > > It would be great if you could contribute the code.
