Sure:
https://speakerdeck.com/sungjuly/apache-usergrid-internal
Slide #21 and on goes over the entity model in detail. Particularly
interesting:
#36
#40
#55-#61
Essentially, Usergrid supports *all* of the basic mongo CRUD operations on
top of Cassandra, passing all of their test cases that don't use any
out-of-the-way functions. Would it be possible to build something similar
*solely* with CQL?
Again, we are at thought exercise at this point, but you through the
gauntlet down :)
I'm fine with Thrift going away - I get the reasoning there. I just want to
be able to hack against ("against", not "on") internals more easily.
