Took a little bit of reading but the OP is founder of company [0] making a massively scalable geospatial database. This is the closest article [1] I can find which has anything close to details. It lists the following technologies:
* A low level stack that bypasses the OS for at least disk IO (supposed to provide a 2-3x throughput increase)
* "polymorphic" space-filling curves for distributed parallel indexing
* hyper-dimensional spatial sieves [2]
* Allen’s Interval Algebra to parallelise SQL statements
More discussion on some of the OP's previous hacker news posts [3].
