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
Obsidian replaces tools like Cron and other popular task schedulers by taking the basic features in a scheduler and adding full management capabilities, workflow, conflict resolution, native load-balancing and failover. Multiple nodes cooperate in job scheduling and execution by using a common database.
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.
- A full job management REST API is included.
- Embedded Java API.
- Seamless Spring integration.
- 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 Obsidian.
- 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.
- Jobs that need to be terminated can be interrupted easily.
- Failed jobs can be resubmitted.
- Submit one-time runs for jobs.
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.
