Hi, I noticed the figure in slide 7 of that presentation and it presents the datastore layers.
However, what i am out for is the figures that shows the visualized relation among GAE datastore, Megastore and Bigtable. For example, Megastore contains GAE datastore, Bigtable contains Megastore, maybe Bigtable can be queried by GQL, etc. Any help is appreciated.
