Mongodb sink connector processing limit

I am using mongodb sync connector.
Through the mongodb sync connector,
Approximately 10,000 data per second, up to 30,000 data is upsert to MongoDB.
That is, 10,000 to 30,000 tps occur, and I wonder if the MongoDB will work without any problem. Too much data seems to be upsert
Is there any way to reduce the upsert load in the mongodb sync connector configuration? I can’t find an answer in the MongoDB Sync Connector official document, so I’m asking a question!
