For mongodb 3.6, the max write batch size is 10,000. Can you change this value and improve mongodb output throughput?
Please refer to https://docs.mongodb.com/manual/reference/method/db.collection.insertMany/

currently the default bulk is 900 and max is 999. IMO I don't see any reason in actually capping the max; I think the user should be responsible in figuring what the max is per their mongo version and adjust if there is a error on write.

I found that this plugin only processes 1k/s when I set bulk as 1000. So how to improve throughput of it?
