Review comment:
IMO, it is OK to have the handleDeleteKeyEvent & handlePutKeyEvent and
writeCountsToDB to take the map as a parameter. They are meant to be stateless
helper methods that act on the input given to them. In the current
implementation, there is an assumption that the task's implementation makes of
the higher level caller, which may not be true in the future.
