I'm using the built in sqlite library on the Android platform.

I'm considering adding several general purpose fields that users will be able to use for their own custom applications, but these fields will be blank most of the time.

My question is, how much overhead will these blank fields add to my database? Do null fields even take up per record memory in sqlite? If so, how much? I don't quite understand the inner workings of a sqlite database.
