I'm using azure data factory with blob storage as an external source (the data table is marked as external).
I've recently restored a data source that had not been providing data, however I'm noticing that it does not recognise that the files are now in the blob store. There file/folder namining conventions have not changed.
Each of my slices for my first pipeline are all marked with the below status:
Waiting: Dataset dependencies
What should I look at to debug this issue? Is there any way to force data factory to re-check for missing files? (the assumption seems to be it will do this automatically, but it isn't picking the files up - I've also tried re-marking the slices to process, but this hasn't helped).
