Overview

The goal of this module is to offer a queue system using the underlying filesystem for storage, security and to prevent race conditions via atomic operations. It focuses on simplicity, robustness and scalability.

This module allows multiple concurrent readers and writers to interact with the same queue. A Perl implementation (Directory::Queue) and a Python implementation (dirq) of the same algorithm are available so readers and writers can be written in different programming languages.

Install

To install this module, run the following commands:

    mvn install
    # or
    mvn package
    # get the jar from target folder

This module is available in the Central Maven Repository so you can simply add to your pom.xml file something like:

    <dependency>
      <groupId>ch.cern.dirq</groupId>
      <artifactId>dirq</artifactId>
      <version>1.8</version>
    </dependency>
