Index tables
Bigtable is incredibly well suited as a structured data storage solution, but lacks support for basic queries. This is due to the fact that all retrieval operations in Bigtable are essentially index scans over ordered data, and Bigtable only supports a single index per row. In order for Datastore to provide some level of query support, multiple index tables are maintained, where the values to be queried are built into each row's index key.
