I'm new to ADF and thought I'd start with something which I thought was easy and is turning into a nightmare! I get errors saying I need to specify the folder and wild card in the dataset when I publish. Dynamic data flow partitions in ADF and Synapse, Transforming Arrays in Azure Data Factory and Azure Synapse Data Flows, ADF Data Flows: Why Joins sometimes fail while Debugging, ADF: Include Headers in Zero Row Data Flows [UPDATED]. Account Keys and SAS tokens did not work for me as I did not have the right permissions in our company's AD to change permissions. I'll try that now. 20 years of turning data into business value. Each Child is a direct child of the most recent Path element in the queue. What is a word for the arcane equivalent of a monastery? Factoid #3: ADF doesn't allow you to return results from pipeline executions. Can't find SFTP path '/MyFolder/*.tsv'. By using the Until activity I can step through the array one element at a time, processing each one like this: I can handle the three options (path/file/folder) using a Switch activity which a ForEach activity can contain. The dataset can connect and see individual files as: I use Copy frequently to pull data from SFTP sources. Please check if the path exists. (I've added the other one just to do something with the output file array so I can get a look at it). I found a solution. Steps: 1.First, we will create a dataset for BLOB container, click on three dots on dataset and select "New Dataset".

To make this a bit more fiddly: Factoid #6: The Set variable activity doesn't support in-place variable updates. childItems is an array of JSON objects, but /Path/To/Root is a string as I've described it, the joined array's elements would be inconsistent: [ /Path/To/Root, {"name":"Dir1","type":"Folder"}, {"name":"Dir2","type":"Folder"}, {"name":"FileA","type":"File"} ]. Oh wonderful, thanks for posting, let me play around with that format. i am extremely happy i stumbled upon this blog, because i was about to do something similar as a POC but now i dont have to since it is pretty much insane :D. Hi, Please could this post be updated with more detail? This is a limitation of the activity. Copying files by using account key or service shared access signature (SAS) authentications. Data Analyst | Python | SQL | Power BI | Azure Synapse Analytics | Azure Data Factory | Azure Databricks | Data Visualization | NIT Trichy 3 The revised pipeline uses four variables: The first Set variable activity takes the /Path/To/Root string and initialises the queue with a single object: {"name":"/Path/To/Root","type":"Path"}. Respond to changes faster, optimize costs, and ship confidently. The path prefix won't always be at the head of the queue, but this array suggests the shape of a solution: make sure that the queue is always made up of Path Child Child Child subsequences. Globbing uses wildcard characters to create the pattern. The folder path with wildcard characters to filter source folders.

Thanks for contributing an answer to Stack Overflow! Point to a text file that includes a list of files you want to copy, one file per line, which is the relative path to the path configured in the dataset.
