Hi @fhueske, the PR has been updated. Temporarily, I keep the logic for
dealing with the late data, as well as the fine-grained cache.
For the late data semantics problem, I think we need to rethink it and make
a final decision (maybe we should consult others). For the cache optimization
problem, I want to leave it a future work. ---
