JNoSQL is a framework and collection of tools that make integration between Java applications and NoSQL quick and easy—for developers as well as vendors. The API is easy to implement, so NoSQL vendors can quickly implement, test, and become compliant by themselves. And with its low learning curve and just a minimal set of artifacts, Java developers can start coding by worrying not about the complexity of specific NoSQL databases but only their core aspects (such as graph or document properties). Built with functional programming in mind, it leverages all the features of Java 8. This session covers how the API is structured, how it relates to the multiple NoSQL database types, and how you can get started and involved in this open source technology.

What defines NoSQL databases?
— No fixed data structure
— Not an ACID, but a BASE
— Five different types
◦ Key/Value
◦ Column Family
◦ Document
◦ Graph
◦ Multi-Model

For example: for a Document DB…
BaseDocument baseDocument = new BaseDocument();
baseDocument.addAttribute(name, value);
JsonObject jsonObject = JsonObject.create();
jsonObject.put(name, value);
Document document = new Document();
document.append(name, value);
ODocument document = new ODocument(“collection”);
document.field(name, value);

… brings a bunch of issues!
— Can’t save asynchronously
◦ No callback
— Can’t define aTime to Live (TTL) for stored data
— Consistency Level choice on persist
— Not all DBs are SQL-based
— There are many NoSQL types
