Submit a Job to the Job Pool Using a Pre-Defined Cron

A Pre-Defined Cron allows you to schedule job submissions to the job pool based on pre-set conditions. In this help section, we are going to go over the steps required to schedule the submission of a job to the job pool using a Pre-defined Cron.

Before you create a pre-defined cron, depending on your job pool type, make sure the following components are configured and present in the Catalyst console:

• Function Job Pool: The Job Function, if initialized through Catalyst CLI needs to be deployed to the Catalyst console.
• Webhook Job Pool: Ensure the URL of the third-party URL is a valid one.
• Circuit Job Pool: Ensure that the Circuit and its associated functions are created and present in the Catalyst console.
• AppSail Job Pool: Ensure you have deployed your AppSail service to the catalyst console.

Once you click Next after configuring the Cron, you will be directed to create the job that the configured cron must submit.

To create the required job:

The Pre-defined Cron will be created, with a unique Cron ID generated by Catalyst. The job the cron is configured to submit will also be created along with its unique Job ID generated by Catalyst. Upon clicking Create, you will be able to view all the details about the created cron and its configurations.

If you wish to test the cron and not wait for the scheduled time, you can submit an immediate job to the job pool by clicking the Submit Job button.

A job will be submitted immediately. The configurations of the job will be the one you configured while creating the cron.

You can view the execution status of the job you submitted by clicking the Execution History button.

The jobs will be listed in the latest order of execution. You can also perform search and filter options on the Execution History operations.
