MinIO also sends with the notifications two headers: `minio-bucket` and `minio-event`. An exchange using the type "headers" can use this information to route the notifications to proper queues.

Note that, you can add as many AMQP server endpoint configurations as needed by providing an identifier (like "1" in the example above) for the AMQP instance and an object of per-server configuration parameters.

- Scheduler: added metrics to record the number of pending pods in different queues ([#75501](https://github.com/kubernetes/kubernetes/pull/75501), [@Huang-Wei](https://github.com/Huang-Wei))

- In a scheduler with `Permit` plugins, when a Pod is rejected during `WaitOnPermit`, the scheduler records the plugin.
  The scheduler will use the record to honor cluster events and queueing `hints registered` for the plugin, to inform whether to retry the pod. ([#119785](https://github.com/kubernetes/kubernetes/pull/119785), [@sanposhiho](https://github.com/sanposhiho))

- Implemented a queueing hint for PersistentVolumeClaim/Add event in the `CSILimit` plugin. ([#124703](https://github.com/kubernetes/kubernetes/pull/124703), [@utam0k](https://github.com/utam0k)) [SIG Scheduling and Storage]

- The `priority_level_request_utilization` metric histogram is adjusted so that for the cases where `phase=waiting` the denominator is the cumulative capacity of all of the priority level's queues.

- Correct event registration for multiple scheduler plugins; this fixes a potential significant delay in re-queueing unschedulable pods. ([#109442](https://github.com/kubernetes/kubernetes/pull/109442), [@ahg-g](https://github.com/ahg-g))
