When there are a lot of files of data on the storage; finding the data that you will need will be difficult. Especially, if the data or bucket is not organized properly. And even if the data has been organized by folders with proper time stamp but no specific data catalog to classify which one is which one it is quite a challenge to find or get the data on time.
