S3 changed AWS Access Key

Hi there!

I had to change my AWS Access Key in Data Lake source, and now looks like I lost the link with the datasets I already created before.

Theres a way to return the link?

Thanks in advance.


Did you change the AWS access key for the S3 source added to Dremio? When you pressed save you should have got a warning that says “You made a metadata impacting change. This change will cause Dremio to clear permissions, formats and reflections on all datasets in this source”, if you had clicked on submit, it would have lost formatting on all the promoted datasets. Are the files Parquet or JSON? If only the above two, you can simply query the dataset and it will automatically format if the below flag in the metadata tab is checked “Automatically format files into physical datasets when users issue queries”

Hope this helps
