An interesting observation that I can't seem to "un-observe" is that Megastore is actually a lot more like MongoDB than one would expect.

Both ostensibly work best when the application fits a hierarchical data model (entity groups vs. documents), and provide out-of-the-box strongly-consistent transactions for a single entity group. MongoDB feels like schemaless Megastore.

Here's a paper with which you might already be familiar, but it's one of the citations for the Megastore paper: http://adrianmarriott.net/logosroot/papers/LifeBeyondTxns.pd.... You'll probably enjoy it (if you haven't already!).
