create the branch if it does not exist.
Review Comment:
Initially, the "Writing to Branches" seemed a first level header (along with
"Writing with SQL" and "Writing with Dataframes"), was it intentional? Do you
think we can just add an example using Dataframe here?
My thought is, then we dont have to repeat this block of text, which we will
have to do if we downgrade it to subsections within "Writing with SQL" and
"Writing with Dataframes".
