HBase GeoIndex?
Hi, does anyone know of any implementation of GeoIndexing on HBase as of
yet?
If not I was thinking of writing one using CoProcessors to increment the
substrings of a GeoHash to help with "number of neighbors" and being able to
filter out points that do not have immediate clusters defined by some value
function.
I am not sure how much benefit this would have yet vs
just de-normalizing the substring points and scanning which is more run of
the mill depending on performance.
Thanx

Given the lack of responses, I think not.

This sounds interesting. Please let us know how it works out if you try it.
