Summary

Bulk write operations should be bucketed by their command, and only split when you reach statement or document size limits. This is a general rule that most drivers follow; however, this behavior is neither clearly specified in a spec.

These is one spec test file that covers such a situation - bulkWrite-comment. But we may want to cover it by a dedicated spec test.

Is this issue urgent?

No

Is this ticket only for tests?

No. Some drivers may need to fix incorrect behavior.
