>
> Legacy coordinator triggers onPartitionsAssigned with empty assignment (which
> is not the case when triggering onPartitionsRevoked or Lost). This is the
> behaviour of the legacy coordinator, and the new consumer implementation
> maintains the same principle. We should review this to fully understand if it
> is really needed to call onPartitionsAssigned with empty assignment (or if it
> should behave consistently with the onRevoke/Lost)
