What does the "f" in "append(f(chunk))" stand for?

Hi @violazhong! I'm drowning in dissertation work right now and just saw this now. So sorry!
The f just means some function you wrote to process the chunk. Usually, you'd select a sub dataframe of each chunk, if the table was too big to fit in memory.
