Obsidian

Obsidian is Carfey Software's Java-based scheduling tool.

It takes the power and expressiveness of Cron and combines it with enterprise-class features like load-balancing, failover and conflict prioritization.

See the User Guide for details of each feature.

Overview

Espresso replaces tools like Cron and Quartz by taking the basic features in a scheduler and adding full management capabilities, workflow, conflict resolution, native load-balancing and failover.

It is a Java-based application, and can be run standalone or embedded within a Java process.

Jobs can be configured and managed from within the administration console, and allow cron-style job patterns, schedule windows and advanced parameterization.

Basic Features

• Cron-style patterns are used for job scheduling.
• Fully-featured administration and monitoring web application.
• Notifications and logging of scheduler events and failures.
• Job configuration can be changed at any time - no restarts or rebuilds.
• One simple Java interface to implement to make a job compatible with Espresso.
• Schedule windows allow you to have future schedule changes (disable a job or change its runtime schedule).
• Job parameterization allows for multiple instances of jobs with different configurations.

Enterprise Features

• Obsidian instances automatically cooperate to perform load-balancing and provide failover.
• Even with a single node licence, a second node may be running in standby to automatically pick up if its peer dies.
• Job conflicts can be configured to provide automatic job prioritization and conflict resolution.
• Jobs may be chained to others based on various conditions to provide job workflow support.
• Floating node licences allow flexibility and choice to users.
