* Elastically scalable throughput and storage: Easily scale up or scale down your DocumentDB JSON database to meet your application needs. Your data is stored on solid state disks (SSD) for low predictable latencies. * Multi-region replication: DocumentDB transparently replicates your data to all regions you've associated with your DocumentDB account, enabling you to develop applications that require global access to data while providing tradeoffs between consistency, availability and performance, all with corresponding guarantees. * Ad hoc queries with familiar SQL syntax: Store heterogeneous JSON documents within DocumentDB and query these documents through a familiar SQL syntax. DocumentDB utilizes a highly concurrent, lock free, log structured indexing technology to automatically index all document content. * JavaScript execution within the database: Express application logic as stored procedures, triggers, and user defined functions (UDFs) using standard JavaScript. This allows your application logic to operate over data without worrying about the mismatch between the application and the database schema. * Fully managed: Eliminate the need to manage database and machine resources. * Tunable consistency levels: Select from four well defined consistency levels to achieve optimal trade-off between consistency and performance.

* Rich Admin Dashboard - View entity statistics, query your database, view indexes, and backup/restore your data. * Multiple Access Methods - Access your data via our JSON API, open-source clients, or community maintained ORMs (Objectify, NDB). * Fully Managed - Cloud Datastore is fully managed, which means Google automatically handles sharding and replication in order to provide you with a highly available and consistent database. * Diverse Data Types - Datastore supports a variety of data types, including integers, floating-point numbers, strings, dates, and binary data among others. * ACID Transactions - Ensure the integrity of your data by executing multiple datastore operations in a single transaction with ACID characteristics, so all the grouped operations succeed or all fail.
