I can't reliably "port" on-prem apps where the concept of MOVE to sub directory is a critical pat of the architecture and workflow of the app. The Irony. I am percent Azure except for my on prem server farm that exists only for my Azure apps to come back down to from the cloud over a VPN to do file access and MOVE operations between directories on the same drive and share.
GetBlobs BlobTraits. None, BlobStates. None, sourceFolder ; await Task. This code prompts us for the path to a local file, the name of a new or existing container, and the name of a new blob. The TransferManager. UploadAsync method performs the upload using this information. Hit F5 to run your application. You can verify that the upload occurred by viewing your Storage account with the Microsoft Azure Storage Explorer.
One feature offered by the Data Movement library is the ability to set the number of parallel operations to increase the data transfer throughput. Keep in mind that many parallel operations in a low-bandwidth environment may overwhelm the network connection and actually prevent operations from fully completing. You'll need to experiment with this setting to determine what works best based on your available network bandwidth.
Let's add some code that allows us to set the number of parallel operations. Let's also add code that times how long it takes for the transfer to complete. Knowing how long it took for the data to transfer is helpful.
However, being able to see the progress of the transfer during the transfer operation would be even better. To achieve this scenario, we need to create a TransferContext object. The former is for transferring a single file and the latter is for transferring a directory of files.
Another convenient feature offered by the Data Movement library is the ability to resume a canceled transfer. Let's add some code that allows us to temporarily cancel the transfer by typing c , and then resume the transfer 3 seconds later.
Up until now, our checkpoint value has always been set to null. Now, if we cancel the transfer, we retrieve the last checkpoint of our transfer, then use this new checkpoint in our transfer context.
It would be disappointing if the Data Movement library could only transfer one file at a time. Luckily, this is not the case. The Data Movement library provides the ability to transfer a directory of files and all of its subdirectories. Let's add some code that allows us to do just that.
There are a few differences between this method and the method for uploading a single file. We're now using TransferManager. By creating a schedule trigger, ADF pipeline can periodically move those files from the source to the destination store. The way that ADF pipeline achieves "moving files" is getting the files from the landing folder, copying each of them to another folder on the destination store and then deleting the same files from the landing folder on the source store.
Be aware that this template is designed to move files rather than moving folders. If you want to move the folder by changing the dataset to make it contain a folder path only, and then using the copy activity and delete activity to reference to the same dataset representing a folder, you need to be very careful.
It is because you have to make sure that there will NOT be new files arriving into the folder between copying operation and deleting operation. If there are new files arriving at the folder at the moment when your copy activity just completed the copy job but the Delete activity has not been stared, it is possible that the Delete activity will delete this new arriving file which has NOT been copied to the destination yet by deleting the entire folder.
This template gets the files from your source file-based store. It then moves each of them to the destination store. Go to the Move files template. Select existing connection or create a New connection to your source file store where you want to move files from.
