Hi @AlexanderFillbrunn I was able to use the new Azure Blob Storage Connector using KNIME 4.3.0! I did the following:
Microsoft Authentication node:
Configured with Authentication mode Shared access signature (SAS) authentication (Azure Storage only), with Blob service SAS URL specified as https://name_of_my_data_lake.blob.core.windows.net?sv={remainder of my SAS token}
connected to
Azure Blob Storage Connector node:
Configured in Settings with Working directory: /directoryname/subdirectory1/subdirectory2/ (the beginning / and ending / are important)
connected to
CSV Reader node with an added File System Connection port on the left
Configured to read a specific CSV file in subdirectory2 with additional settings to specify the layout of the CSV file
Thanks to you and the KNIME developers who made this possible!
