Using TiKV as the metadata engine for JuiceFS,

juicefs format \
    --storage s3 \
    ... \
    "tikv://192.168.1.6:2379,192.168.1.7:2379,192.168.1.8:2379/jfs" \

I would like to ask, can a token be configured here, so that only the key can access the metadata protection mechanism?
Additionally, can different tokens be configured for different prefixes? Thanks!

Is the usage scenario of TiKV here to work as a distributed KV storage system?

Only through the TiDB entry configuration can the Token method be supported, and it must be the authentication-related security mode of the MySQL protocol.

Currently, the encryption mode that TiDB can support is used to protect data transmission security, not this kind of Token access protection mode.
For your reference!

TiDB supports encryption mode, but the configuration method may be different.
