Are we still locked to an old version of Redis?

@geoHeil Thanks, that's more or less what I intended to say with "grid all points and use the grid cells to speedup the filtering step", maybe I did not use...

It would be great to support 3D points at least because we could load LiDAR data sets (PointClouds) which are composed of billion of 2,5D points. It would be a...

Yes, I thought the same. Such feature would be very welcomed. For now we are just exploring geotrellis, geotrellis-pointcloud and PDAL and once we start using it for our projects...

It has 13 dimensions. Assuming 6 of them are doubles and the other 7 are integers (we are overestimating) a record would be: (6*8 + 4*7) 91M = 6.6GB which...
