I think the best option would be to have a separate

threaded model.
This makes me think we should need to create one executor
per DP, each one using just one thread: additional benefit is
that no locking would be needed, we can remove all barriers
in the backend (unless batch mode enables concurrent usage of the
IndexWriter)
Hmm, sounds a little counterintuitive to me. Is the whole idea behind the
Executor framework not
to have a single Executor which is backed by a pool of threads? Then
again, I am not
so familiar with this. Just a thought.
Removing barriers sounds good though :)
