MongoDB will accommodate loading CSV without regard to schema while
still creating identifiable "columns" in the database, but you'll have
to predict or back-impose some schema later if you're going to create
indices for fast searching of the data. You can perform searching of
data without indexing in MongoDB, but it's slower.
Cassandra will require you to understand the schema, i.e.: what the
columns are up front unless you're just going to store the data without
schema and, therefore, without ability to search effectively.
As suggested already, you should share more detail if you want good
advice. Both DBs are excellent. Both do different things in different ways.
Hope this helps,

I need to make a decision on Mongo DB vs Cassandra for loading the csv
file data and store csv file as well. If any of you did such study in
last couple of months, please share your analysis or observations.
