Option 1 is less efficient, because it requires a query. Incidentally, note that if you want exactly one result, you can call
get()on the Query, which will return the first result, or None if there are none.2 and 3 are identical;
get_by_idis just syntactic sugar for constructing a key and fetching it withget.
