+### Recovery queue
+
+The recovery queue, identified by the name `root.@recovery@`, is a dynamic
queue that is not directly queryable. It is used exclusively during the
initialization phase for already running allocations that are part of
applications failing placement. Its primary function is to handle tasks that
need to be reassigned or recovered without user intervention.
+
+- The queue is created dynamically and will disappear when it is no longer in
use.
+- The queue does not have quotas or Access Control Lists (ACLs).
+- It cannot be submitted to directly by users. It is managed internally by
YuniKorn for specific recovery operations.
+- While the queue is unqueryable directly, its existence and activities can be
observed through the application RESTful API at
[/ws/v1/partition/:partition/applications/:state](../api/scheduler#partition-applications).
+
### Placement rules
The placement rules are defined and documented in the [placement
rule](placement_rules.md) document.
