Note: This package is a work-in-progress, and may occasionally make backwards-incompatible changes.
Documentation and examples are available here.
Google Cloud Datastore (docs) is a fully managed, schemaless database for storing non-relational data. Cloud Datastore automatically scales with your users and supports ACID transactions, high availability of reads and writes, strong consistency for reads and ancestor queries, and eventual consistency for all other queries.
Follow the activation instructions to use the Google Cloud Datastore API with your project.
