Arangodb Introduction--unknown architecture and underlying principles

Arangodb Introduction

Arangodb is an open source NoSQL database, official website: https://www.ArangoDB.org/

ARANGODB supports flexible data models such as document documents, graph graphs, and key-value pairs key-value storage. Arangodb is also a high-performance database that uses class-SQL queries or JavaScript extensions to build high-performance applications.

Arangodb is a laudable point to be able to run ARANGODB version 1.4 on Raspberry Pi.

Features of the ARANGODB:

1) Multi-model database

You can flexibly use key-value pairs, documents, graphs, and combinations to build your data model.

2) Convenient Enquiry

ARANGODB has a SQL-like AQL query language, and can also be queried in restful mode.

3) can be extended via JavaScript

There are no language-scoped restrictions, and you can use the same language from the front-end to the back-end.

4) High Performance

Arangodb extremely fast speed

5) Foxx-Build your own API

Build applications with JavaScript and Arangodb, Foxx run inside the DB for fast access to data.

6) High Space utilization

Compared to other document databases, Arangodb occupies less storage space because Arangodb is a schema free meta-data pattern.

7) Easy to use

Arangodb can start running in a matter of seconds, and you can use the graphical interface to manage your arangodb.

8) Multi-OS support

ARANGODB supports operating systems such as Windows, Linux, and OSX, and also supports Raspberry Pi.

9) Open Source and free

Arangodb Open Source is free, it uses the Apache 2 license agreement.

10) Copy

ARANGODB support for master-slave clusters

Simply say Aerospike installation, my side has a server is Ubuntu, then use it. If there is Docker, then the iers is good. Just download Image,run a bit.

' Http://aerospike.com/download/server/latest/artifact/ubuntu12 '  -xvf aerospike.tgzcd aerospike-server-community-*-ubuntu12sudo. # Would install the. RPM Packagessudo service aerospike start &&-f/var/log/aerospike/ Aerospike.log | grep cake

Sometimes you start manually.

Sudo/etc/init.d/aerospike start

In addition, you can learn the Aerospike library of Python. Python

#Import the moduleImportAerospike#Configuration for the clientConfig = {  'hosts': [ ('127.0.0.1', 3000) ]} #Create a client and connect to the databaseClient =aerospike.client (config). Connect ()#Records is addressable via a tuple of (namespace, set, key)Key = ('Test','Demo','Foo') #Write a recordClient.put (key, {'name':'John Doe',  ' Age': 32}) #Read a record(Key, metadata, record) =client.get (Key)#Close Connection to ClusterClient.close ()

Performance comparison See Http://www.infoq.com/cn/news/2013/04/NoSQL-Benchmark overall seems to be better than MongoDB if you make full use of memory speed!
