Java and JavaScript Client APIs

MarkLogic's Java and Node.js Client APIs are built on top of the MarkLogic REST API described in MarkLogic REST API Reference.

The Java API enables programmers to use MarkLogic without having to learn XQuery, and can easily take advantage of MarkLogic's advanced capabilities for persistence and search of unstructured documents.

MarkLogic also supports JavaScript middleware in the form of a Node.js process for network programming and server-side request/response processing.

JavaScript

Web. JavaScript is an object-oriented computer programming language commonly used to create interactive effects within web browsers, whose implementations allow client-side scripts to interact with the user. It is also being used in server-side network programming (with Node.js), game development and the creation of desktop and mobile applications.

JFS (Journaling File System)

MarkLogic. A journaling file system is a file system that keeps track of the changes that will be made in a journal (usually a circular log in a dedicated area of the file system) before committing them to the main file system. In the event of a system crash or power failure, such file systems are quicker to bring back online and less likely to become corrupted.

job

Hadoop. The top level unit of work for a MapReduce system. A job consists of an input data set, a MapReduce program, and configuration properties. Hadoop splits a job into map and reduce tasks which run across a Hadoop cluster. A Job Tracker node in the Hadoop cluster manages MapReduce job requests.

join host

A static host in an existing cluster through which a dynamic host can join a particular group by presenting its dynamic host token to the join host Admin app server. [New in v12.0.0]

JPA (Java Persistence API)

Java. The Java Persistence API provides a Plain Old Java Object (POJO) persistence model for object-relational mapping.

JSON (JavaScript Object Notation)

JavaScript. A text-based open standard language for representing simple data structures and objects.

JSON Web Signature (JWS)

Security. The signature component of a JSON Web Token (JWT). [New in v11.2.0]

JSON Web Token (JWT)

Security. A compact, URL-safe, encoded token that asserts a set of claims with a signature. [New in v11.2.0]

JSON-LD (JavaScript Object Notation-Linked Data)

JavaScript. A WC3 recommended format for transporting linked data an RDF graph, or an RDF Dataset in a JSON syntax, allowing data to be serialized in a way that is similar to traditional JSON.

JWS

Security. See JSON Web Signature.

JWT

Security. See JSON Web Token.

JWT Secret

Security. The signature key used to generate the JSON Web Signature (JWS). [New in v11.2.0]
