Is hot reload for user and password creds available?

[msberyanov]

Hi @lburgazzoli.

We have a task to hot reload creds to etcd (they can be changed from vault). Is it allowed in your library? How to process situations where watches on key are already set and currently listening? Should I recreate client every time creds change? How would you do this?

Thank you.

I guess it is fine to change user, password fields in ClientConnectionManager through builder() and then AuthCredential will update token with new info?

Thank you! Tell me please what to do?

@lburgazzoli ?

As today we have a ClientBuilder.user and ClientBuilder.password methods, so I guess we should introduce a new interface, something like:

interface AuthCredentialProvider {
    ByteSequence username();
    ByteSequence password();
}

So you can plug it with your vault based solution. But mind that, this is the first thing I have on top of my mind.

IBM/etcd-java#101 I have done it in the neighbouring lib. Most likely it is either done in yours, or should be done. It is working.

as I said, it should be done if you want to have something working reliably
