In this article, there are two models: a Hero and Villain. To integrate Java and ArangoDB, we're going to use Eclipse JNoSQL, an open-source project that easily bridges JavaEE over the NoSQL database. How to Install Using Dockerĭocker run -e ARANGO_NO_AUTH=1 -d -name arangodb-instance -p 8529:8529 -d arangodb/arangodb JavaEE vs. To get more comparison between them, click here. SELECT * FROM users WHERE active = 1 //SQLįOR user IN users FILTER user.active = 1 RETURN user //AQL Despite such differences, anyone with a SQL background should have no difficulty in learning AQL. This query looks like a SQL language, though there are slight differences, such as FILTER instead of WHERE. In ArangoDB, a developer can store data as key/value pairs, graphs, or documents, and access any or all of the data using a single declarative query language thanks to AQL, or ArangoDB Query Language. VelocyPack (VPack): A binary JSON that ArangoDB uses to store its data that is self-contained, is compact, covers all of JSON plus dates, integers, binary data, and arbitrary precision numbers, can be transferred to JSON and from JSON rapidly, and avoids too many memory allocations.ĪrangoDB Query Language (AQL): 1 Language, 3 Databases.Fault tolerance: ArangoDB has an efficient fault-tolerance system that is enabled by default.When working with single-model databases, this can lead to various operational challenges. ![]() ![]()
