Datastore is a slightly different beast, they handle all the underlying node work for you , so you are not scaling your cluster. They also provide a SQL like interface for querying your data which in big table would be completely on your implementation. There exists some logical boundaries by using `namespaces` (Inherently tables) and then the `kind` for further selection. When you query bigtable you can provide column / various filters on what type of data you would like to return or truncate. The problem with that is most of the filters at the bigtable level are regex based and can be resource intensive. The better approach with bigtable is to design a table (row key) for each type of query you would want to ask the DB.
