Move Files from Multiple Folders to Multiple Folders in Azure Blob - azure

Question

I have a folder structure in Azure Blob like this
Container/app_archive/app1/app1.csv
Container/app_archive/app2/app2.csv
Container/app_archive/app3/app3.csv
Container/app_archive/app4/app4.csv
Container/app_archive/app5/app5.csv
....
Container/app_archive/app150/app150.csv
These needs to be moved to Container/app_archive/app1/YYYY/MM/DD/app1.csv
Container/app_archive/app2/YYYY/MM/DD/app2.csv
.....
Container/app_archive/app150/YYYY/MM/DD/app150.csv
Whenever any file is placed in any folder, it has to trigger and copy the files accordingly. Also I need to capture this information in an audit table like Source File Name, Source File Path, Destination File Path etc etc. How to achieve this ?

Answer 1

You can use Storage event triggers with Dataset parameters for this like below.
First Give the Root container and Blob path ends with as .csv in Storage event trigger.
Create two pipeline parameters and assign the trigger values to those while creating trigger.
Now, create dataset parameters for folder name and file names for both source and sink datasets.
Source:
Sink:
My pipeline JSON:

Result when a file uploaded to app1 folder:
