Abe Ratnofsky commented on CASSANDRA-19380:
-------------------------------------------
Can you share more about why you need to interrupt existing connections?
Typically it's sufficient to wait until the next natural reconnection attempt,
since already-authenticated connections are not impacted by credential
rotations where the password for a given user changes.
> Enhance CqlSession to refresh the auth credentials dynamically

> Key: CASSANDRA-19380
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19380
> Project: Cassandra
> Issue Type: Improvement
> Components: Client/java-driver
> Reporter: Ranjith Gampa
> Priority: Normal
>
> Our team is working on a feature to automatically deliver the credentials to
> application when the credentials are rotated without application teams
> restarting the application. Is this currently supported with
> "com.datastax.oss.driver.api.core.CqlSession"? If yes, please provide a
> sample code for the same.
>
> If this feature isn't supported, is it feasible to enhance? Below is our
> request,
> # To dynamically refresh the credentials at runtime within existing
> CqlSession instance.
> # Internally drain the old connections gracefully in resilient manner and
> establish the new connections with new credentials without doubling the
> overall number of connections.
>
> This is how we currently set the auth credentials at application startup.
>
> {code:java}
> cqlSessionBuilder.withConfigLoader(driverConfigLoader)
> .withAuthCredentials(userName, password); {code}
