Description
When trying to use insert of update to upload a row in which there is a file(ByteString), it might be failed. It will not return any error or msg, but just wait, unless pass Ctrl+C. Build with same codes, PostgreSQL worked well.

Research direction
Start by reproducing the hang in the persistent-mongoDB backend with insert or update and a ByteString larger than about 128k; compare the same operation with PostgreSQL. Trace the MongoDB upload path from those operations and determine where the request stops progressing. Done means large file uploads complete or return an error instead of waiting indefinitely.
