No, you can (and should) just write the entire object each time, at least in my experience.
You will create new versions of the Cells that you are overwriting with the same value, but you will definitely be paying less of a cost than you would with requiring a read and diff before each write.

The column family Details consists of name, address, and email. Now I have a Person object which corresponds to this row. This object contains name and address but email is null. In order to update the row with the new data from the Person object. I have to read the row, compare it with my object and store only the difference. Is it correct? Thank you for your cooperation, M.
