Are writes ordered?

[ronag]

I see that we are using napi_create_async_work. However, I can't read anywhere whether or not work items are guaranteed to be executed in order or not. If not then we might have a problem with write ordering, i.e. preceding writes overwriting following writes.

Do we need to create our own per db ordered work queue?

Writes are not ordered (at least by design, and I doubt that napi_create_async_work is ordered, seeing as its purpose is parallel work). For the majority of users that's perfectly fine. Introducing a work queue would be a major change, and quite complicated, so I want to see many upvotes before considering it. Until then it can be handled in userland, where you have a choice of doing things in parallel or sequentially.

I think we might need to add a clear warning for this in the docs. I for one assumed that they would be ordered.

That would be good. PR welcome.
