Cloud Datastore

Cloud Datastore is a schemaless NoSQL datastore in Google's cloud.

• Applications can use Datastore to query your data with SQL-like queries that support filtering and sorting.

• Datastore replicates data across multiple datacenters, which provides a high level of read/write availability.

• Datastore also offers automatic scaling, strong consistency for reads and ancestor queries, eventual consistency for all other queries, atomic transactions, and no planned downtime.

Find Datastore in the left side menu of the console, under Storage.
