Can I use 'mongodb kafka connector' with cluster that real-time updates are performed?

I want to use ‘mongodb kafka connector’ to copy MongoDB cluster.
Our MongoDB cluster is performing updates in real time. (2000 update per second)

In this case, can I use ‘mongodb kafka connector’?
I want to copy all exist data and I want all updates to be reflected in the copy cluster.
(“startup.mode” is “copy_existing”)
