****** ArangoDB ******
|
||||
ArangoDB is a multi-model, open-source database with flexible data models for
|
||||
documents, graphs, and key-values. Build high performance applications using a
|
||||
convenient SQL-like query language or JavaScript extensions. Use ACID
|
||||
transactions if you require them. Scale horizontally with a few mouse clicks.
|
||||
The supported data models can be mixed in queries and allow ArangoDB to be the
|
||||
aggregation point for your data.
|
||||
To get started, try one of our 10 minutes tutorials in your favorite
|
||||
programming language or try one of our ArangoDB_Cookbook_recipes.
|
||||
For the impatient: download and install ArangoDB. Start the server arangod and
|
||||
point your browser to http://127.0.0.1:8529/.
|
||||
***** Key Features in ArangoDB *****
|
||||
* Multi-Model: Documents, graphs and key-value pairs — model your data as
|
||||
you see fit for your application.
|
||||
* Joins: Conveniently join what belongs together for flexible ad-hoc
|
||||
querying, less data redundancy.
|
||||
* Transactions: Easy application development keeping your data consistent
|
||||
and safe. No hassle in your client.
|
||||
Here is an AQL query that makes use of all those features:
|
||||
[AQL Query Example]
|
||||
Joins and transactions are key features for flexible, secure data designs,
|
||||
widely used in relational databases but lacking in many NoSQL products.
|
||||
However, there is no need to forgo them in ArangoDB. You decide how and when to
|
||||
use joins and strong consistency guarantees, without sacrificing performance
|
||||
and scalability.
|
||||
Furthermore, ArangoDB offers a JavaScript framework called Foxx that is
|
||||
executed in the database server with direct access to the data. Build your own
|
||||
data-centric microservices with a few lines of code:
|
||||
Microservice Example
|
||||
[Microservice Example]
|
||||
By extending the HTTP API with user code written in JavaScript, ArangoDB can be
|
||||
turned into a strict schema-enforcing persistence engine.
|
||||
Next step, bundle your Foxx application as a docker_container and get it
|
||||
running in the cloud.
|
||||
Other features of ArangoDB include:
|
||||
* Schema-free schemata let you combine the space efficiency of MySQL with
|
||||
the performance power of NoSQL
|
||||
* Use a data-centric microservices approach with ArangoDB Foxx and fuse
|
||||
your application-logic and database together for maximal throughput
|
||||
* JavaScript for all: no language zoo, you can use one language from your
|
||||
browser to your back-end
|
||||
* ArangoDB is multi-threaded - exploit the power of all your cores
|
||||
* Flexible data modeling: model your data as combination of key-value
|
||||
pairs, documents or graphs - perfect for social relations
|
||||
* Free index choice: use the correct index for your problem, be it a skip
|
||||
list or a fulltext search
|
||||
* Configurable durability: let the application decide if it needs more
|
||||
durability or more performance
|
||||
* Powerful query language (AQL) to retrieve and modify data
|
||||
* Transactions: run queries on multiple documents or collections with
|
||||
optional transactional consistency and isolation
|
||||
* Replication and Sharding: set up the database in a master-slave
|
||||
configuration or spread bigger datasets across multiple servers
|
||||
* It is open source (Apache License 2.0)
|
||||

|
||||
***** Latest Release - ArangoDB 3.0 *****
|
||||
The What's_new_in_ArangoDB_3.0 can be found in the documentation.
|
||||
Key features of the 3.0 release are:
|
||||
* use of VelocyPack as internal storage format
|
||||
* AQL improvements
|
||||
* much better cluster state management
|
||||
* Synchronous replication (master/master)
|
||||
* unified APIs for CRUD operations
|
||||
* persistent indexes
|
||||
* upgraded version of V8
|
||||
* new web admin interface
|
||||
* Foxx improvements
|
||||
* Logging improvements
|
||||
* improved documentation
