Synergy Scheduler is a production-grade Job Scheduling System. It breaks time into intervals, associates every interval with a job and makes sure that no job is missed and that each job is completed in the right order.
Common use-cases:
- wait with starting the daily jobs until all nested hourly are successfully finished
- mark daily and other dependant jobs for reprocessing, should an hourly be manually triggered for reprocessing
- run a job every 30 minutes or two times per day on Tue, Thu and Fri
Synergy Scheduler use of Rabbit MQ for communication with subsidiaries makes it a good choice for deployments where part of the system is remote or machine/location dependent.
Synergy Scheduler is supervising triggering and life-cycle for two types of jobs:
- cron-like jobs govern by timer. They are known to the system as free-run
- managed jobs that are govern by state machine. Such jobs could have multiple dependencies on other jobs
Here, term job corresponds to an execution of any system process (for example: Python process, Hadoop map-reduce job, etc) with a set of particular arguments, started and monitored by the Synergy Scheduler means.
Each process registered within the Synergy Scheduler could chose state machine to govern its execution.
To start using Synergy Scheduler user would have to write an actual job and register it within the context.
