Subject [jira] [Commented] (ACCUMULO-164) Add support for wildcards/regexes in locality group setting.
Date Thu, 07 Feb 2013 02:01:13 GMT


Josh Elser commented on ACCUMULO-164:

Well put, [~ctubbsii]. I agree with everything you say.

A bit off to the side: I think one of the best lesser-realized "features" of Accumulo falls
into the fact that column families are not fixed. To this extent, I think your final point
about creating this functionality in an "expert" mindset further enhances the ability to support
unlimited column families.

The feature in its simplest sense does conflict with the original idea behind locality groups,
but is that always "bad"? I'm not sure, but it's definitely different. 

Do you have any ideas on how to present such a feature that would avoid steering the common
user toward it? Is healthy warning/documentation sufficient?

> We should look into adding the ability to specify locality group columns as either wildcarding
or regexes. I'm unsure of the feasibility of this, hence the lack of fix date.
