Does Neptune execute bulk loader jobs in parallel or serially?

A new bulk load request is only accepted if there is no active load.
Bulk loader executes one single request at any given time.
Within a single bulk load, Bulk loader loads data in parallel threads, non-atomically. And the order in which data is solely decided by the bulk loader, user cannot control the order in which data gets inserted.

We have plan to support new bulk load requests be queued up and executed one by one from the queue.
