Hi Team,

I am using spark-mongo connector version 3.0.1 for migrating data from Sharded MongoDB cluster. 
I wanted to know, how can be control the number of parallel connection from spark to MongoDB. As per DBA there are 4000 connections are spawned for my query and still the result isn't come. 
So if anybody can help to identify how to control this parallel threads, I didn't find any mention of it in the official documentation.
