Improvement
The queueing mechanism for the active session queue changed from a FIFO queue to a prioritization-based queue respecting the session's CPU weight from the corresponding consumer group.
Consequence
Queued sessions with a higher CPU weight (defined in the consumer group) receive an active slot before sessions with a lower CPU weight, which reduces waiting time for queued high-priority sessions.
