Passing values between notebook tasks in Workflow Jobs

[brickster]

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..

Hope everything is going great.

Does @Uma Maheswara Rao Desula​  response answer your question? If yes, would you be happy to mark it as best so that other members can find the solution more quickly?

We'd love to hear from you.

Thanks!

@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
