I am facing an issue where the expected date partition folder should be named in format like "campaign_created_date=2024-01-17", but instead it is writing as "ad", "8B" looks like a random folder names.

Usually it will be like below:


Now it changed like below:

When I searched on net I got some info like if MinWorkerVersion is greater than 2 will make this variation in folder name. But it is not clear for me. 

Can anyone let me know why this is happening suddenly? I would like to know how the MinWorkerVersion changes will affect the folder names and its Pros and Cons. What is the reason behind it.
