I think this needs a more elaborate Javadoc on what this means, as most users won't understand this automatically. I would suggest something like:

Suggested change

/** Sets the database role that should be used by this instance. */

/**

* Sets the database role that should be used for connections that are created by this instance.

* The database role that is used determines the access permissions that a connection has. This

* can for example be used to create connections that are only permitted to access certain tables.

I agree that we should remove this, as it is no longer needed, BUT:

We should consider doing so in a separate PR. It is not related to this change.

We should do it in a non-breaking way. Anyone who currently has dialect=... in their connection string will get an error after this change. We should therefore silently ignore it if we encounter dialect=... in a connection string.

Reverted the change to remove Dialect, will be done in another PR

I don't think users will understand what 'creator role' means. This seems like an internal name (I (think I) understand that it means the role that is used to create a session, but that is not clear to a user.)

I would suggest: The database role that is used for this connection. Assigning a role to a connection can be used to for example restrict the access of a connection to a specific set of tables.

Although the probability is low that it goes wrong, it would be better to use an AtomicInteger for this, as our integration tests can run in parallel.

Looks generally good to me, except we need some Javadoc for the version argument, as it is not self-explanatory.

What is the 1 here?

EDIT: Apparently this is a version number. Should we add the version as an argument to the getIAMPolicy method?
