* Single Instance - You can use ArangoDB as a specialized database for key/values, documents or graphs and even mix up those data models in one query. * Cluster - Synchronous replication. Automatic failover. Self-organizing cluster state management. Fast cluster startup. Easy maintenance. Multiple data models. All with an ArangoDB Cluster. * Mixed Services - Modern Architectures demand scalability, polyglot persistence and low maintenance. Modern data center operating systems put your data cluster on autopilot. * Graph - ArangoDB provides also the full feature set of a mature graph store (e.g. pattern matching, shortest path, full blown traversals) and due to a little magic it can perform graph queries very fast compared to many other leading graph solutions. * Document - You can store as many attributes in a document as you like (default size of a document is 32MB, but configurable to your needs). ArangoDB has a wide feature-set for querying and working with documents like joins, secondary indexes or acid transactions. You can horizontally scale join usage to the technically possible.

* 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.
