Can you provide some more details on the data you want to store and queries you want to run ?
That's a good question, Bill.
The data that I'm trying to store begins as a simple point. But, moving fo=
rward, it will become more like complex geometries. I assume that I can si=
mply create a JSON-like object and insert it. Which, for now, that works. =
I'm just wondering if theres a typical / publicly accepted standard of sto=
ring somewhat complex spatial data in Cassandra.
Additionally, I would like to figure out how one goes about slicing on large spatial data sets given situations where, for instance, I would like to get all the points in a column-family where the point is within a shape. I guess it boils down to using a spatial comparator of some sort, but I haven't seen one, yet.

I know nothing about postgis and little about spacial data, but if you're simply talking about data that relates to some latitude & longitude pair, you could have your row key simply be the concatenation of the two: lat:long.
Can you provide more details about the type of data you're looking to store?
