Azure Data Factory Dataflow Costs

Devlin, Gannon 1 Reputation point

I'm a bit confused on pricing and would really appreciate any clarification.
How is the same pipeline costing me $1.30 when ran thru debug but $6 when ran on a trigger?
I understand there is the cluster startup time but each dataflow is taking more than 10x longer and running up significantly more vcore hours
Is there anything I can do to reduce these costs besides purchasing reservations?
I'm running them on an general purpose IR with 8 cores and 0 ttl
I'd like to run the pipeline 4x a day but $24/day for one pipeline seems like a lot

    Hi @Devlin, Gannon ,

    Welcome to Microsoft Q&A platform and thanks for posting your question.

    I understand your query is related to billing of the Dataflow execution.

    Debug executions from pipelines and data preview debugging will continue to use the debug settings which has a preset TTL of 60 minutes.

    • If you set a TTL, ADF will maintain a pool of VMs which can be utilized to spin-up each subsequent data flow activity against that same Azure IR. This reduces the amount of time needed to start-up the environment before your job is executed.
    • ADF will maintain that pool for the TTL time after the last data flow pipeline activity executes. Note that this will extend your billing period for a data flow to the extended time of your TTL. However, your data flow job execution time will decrease because of the re-use of the VMs from the compute pool. The compute resources are not provisioned until your first data flow activity is executed using that Azure IR.
    • For more specialized assistance on this, I recommend you to create a billing support ticket which is free of cost. The ticket enables you to work closely with the support engineers and get a quick resolution to your issue.


    You can also contact Azure Billing/subscription support, which is free, and it's the best choice for your scenario.


    If you have questions or need help on how to create a support request, here are the steps to create support case: How to create a support ticket for Azure billing and subscription issues and OR Call to Global Customer Service phone numbers.
