Hackers,
I've got my patch with double sorting picksplit impementation for GiST into
more acceptable form. A little of testing is below. Index creation time is
slightly higher, but search is much faster. The testing datasets were
following:
1) uniform dataset - 10M rows
2) geonames points - 7.6M rows
I've looked at the patch, and took a brief look at the paper - but I
still don't understand the algorithm. I just can't get my head around
the concepts of split pairs and left/right groups. Can you explain that
in layman's terms? Perhaps an example would help?
