Passing values between notebook tasks in Workflow Jobs

brickster — Sun, 30 Oct 2022 09:58:20 GMT

I have created a Databricks workflow job with notebooks as individual tasks sequentially linked. I assign a value to a variable in one notebook task (ex: batchid = int(time.time()). Now, I want to pass this batchid variable to next notebook task.

What is the best option to pass this variable to the next notebook? Is using widgets the only option to pass?

Hi @Saravanan Ponnaiah

Stumbled across this old question so answering just in case.

You can use dbutils.notebook.exit and exit the 1st notebook with that batchid variable. You can then collect this variable in you next linked notebook.

Hope this helps..

Cheers..

@brickster You would use dbutils.jobs.taskValues.set() and dbutils.jobs.taskValues.get().

See docs for more details: https://docs.databricks.com/workflows/jobs/share-task-context.html
