Hello. 

We are using Ceph storage to test whether we can run the service by uploading and saving more than 40 billion files.

So I'd like to check the contents below.

1) Maximum number of Rados gateway objects that can be stored in one cluster using the bucket index
2) Maximum number of Rados gateway objects that can be stored in one bucket

Although we have referred to the limitations on the number of Rados gateway objects mentioned in existing documents, it seems theoretically unlimited

If you have operated the number of files at the level we think in actual services or products, we would appreciate it if you could share them.

Below are related documents and related settings values.
