Is "Real time spatial database" just a fancy word for another distributed, in-memory datastore? There are many implementations of distributed data structures, and many are used for in-memory analytics. I realize spacebase also minimizes remote lookups/puts in the average case. I just want to understand the "spatial" aspect they try to integrate into their product.
The spatial aspect comes from the ability to efficiently answer queries such as "what is set of objects within the following cube?" , etc. Look up R-Trees if you're curious.
