Parquet File Loading in Dataflow

[nklytics]

Hi

I tried loading parquet file from my OneDrive of size 200MB in power bi dataflow but it throw an error of 

Parquet.Document cannot be used with streamed binary values. It works well with parquet file of smaller size. I am attaching the screenshot with the error. is there any solution for this error?

Hi @nklytics ,

Thanks for using Fabric Community.

Apologies for the issue you have been facing. I would like to check are you still facing this issue? 
It's difficult to tell what could be the reason for this performance. I would request you to wait for sometime and try again. You can also try to upload the file directly, not through OneDrive and check it.
 

If the issue still persists, please reach out to our support team so they can do a more thorough investigation on why this it is happening: Link

Hope this helps. Please let us know if you have any other queries.

Thanks for reponse.

It is working perefectly fine with dataflow gen2 but not with power bi dataflow.

It also works fine when connecting with Local file in Power BI Desktop.

Thanks

Hi @nklytics, right now the Parquet connector only supports reading files from the local system, Azure Blob Storage and ADLS Gen 2. Reading from other sources, even if it may appear to work under certain circumstances or within certain constraints, is not supported.
