How to create Azure Data Factory pipeline to injest new csv files from SFPT server's folder few times a day


I am having a lot of issue with Trigger in Azure Logic App for at least a month now.
Somehow, Trigger does not grab csv files as expected.
It was working fine for a while (maybe 2-3 months), but then as more files are loaded in SFTP folder, somehow, Trigger does not grab more than 4-5 files even though I changed the frequency from something like every 1 hour to every10 minutes.

I did some initial research which one to use, and some say Logic App should be (due to trigger).

But, there is other suggestion to use ADF (Azure Data Factory):

Business requirement is that we need to somehow ingest csv files' data on a daily basis, but it does not necessarily have to be in a real time.

It could possibly run to grab whatever the new files like 3 times a day (6 am, 8 am, 10 am).

Can ADF fulfill the requirements?

    Hi @Anonymous ,

    Thank you for posting query in Microsoft Q&A platform.

    You can achieve this using Azure data factory. Below are the few work arounds.

    Approach1: Use GetMetaData activity to get list of files from folder and then use ForEach activity to loop them and inside ForEach activity use Copy activity to copy each file. Here Inside copy activity we should use parameterized datasets.
    Please note, here after copy activity we should log copied filenames to some log table. And Before copy we should check if that file is already copied or not by comparing with log table. We can use Lookup activity or Script activity to run SQL query to check if file name presents or not in log table.

    Approach2: Using Wild card file path in Copy activity.
    Inside Copy activity use wild card file path to point to all files and then use Filter By last modified filed values to filter files based on last modified times to Copy.

    Refer below video for better understanding of Approach 2.

    Script Activity in Azure Data Factory or Azure Synapse

    Hope this helps. Please let me know if any further queries.
