      Description

      I attempted to serialize over 2.8GB of data in one go using a stream to a file on my disk, and was unable to complete the operation due to the below exception. I was originally using a pretty old version of the driver and ran into a similar integer overflow issue, so when I upgraded I decided to check whether it also affects this version, which it does.

      The root cause seems to be that I am trying to serialize more bytes than the Position data type can track, resulting in an overflow. I have also attached a very simple project which reproduces the issue (on my machine at least).

      I'm sure that the workaround provided will be to split the data up but I noticed the implementation changed since my previous version to use streams rather than buffers so I had hoped this would have solved the issue.

      Thank you!
