Hi Sumedh.

Judging by the numbers (25 GB, 17GB), I assume that there is a very huge data set you are trying to download without enough pre-filtering.
CDF is not a file, so it’s not something that is easy to pull in one go.

To make this fast you’d need to use server-side (push-down) filters.
It is recommended selecting a subset of data by filtering the resources by specific fields (E.g. externalId, data set id, etc).
