Q: I want to be able to schedule a job to run every other week on Tuesday. But I can’t seem to add it into the Matillion ETL job scheduler. Is there a way to add schedules that aren’t straightforward, like starting a job once per week?
A: Great question, as we all have schedules that can be a bit more complex. The Matillion inbuilt scheduler is a cron-like scheduler. It is great for scheduling simple intervals for Matillion ETL jobs from within the tool itself. But there are some complex schedules that cannot be specified in the scheduler – for example the schedule you mentioned or a job that needs to be scheduled to run on the last day of the month. But there is a way to add these schedules, even if the scheduler does not natively handle them.
Scheduling complex jobs in Matillion ETL
Option 1: Using ‘If’ component in Advanced mode
Here is the job setup:
The first condition evaluates if the day is a Tuesday (day numbers go from 1 to 7, with Monday being 1) and the second condition evaluates if the week is an even week.
Option 2: Using the Python Script component along with the ‘If’ component in Basic mode
We can also use the Python Script component to calculate the day number and the week to set job variable values. Those variables can then be used in the ‘If’ component to evaluate the values and run the subsequent jobs and steps per the scheduling requirement.
This is the job setup for Option 2:
Here are the settings for the job variables:
Here is the Python 3 script to use:
And here are the conditions in ‘If’ component (Simple Mode):
With either of these two options, you should be able to accommodate most complex schedules by changing the conditions per the scheduling requirement.
