tasks - Nodetool supercommand for managing task manager tasks.
Task manager is an API-based tool for tracking long-running background operations, such as repair or compaction, which makes them observable and controllable. Task manager operates per node.
When a task completes, its status is temporarily stored on the executing node
Status information is retained for up to task_ttl_in_seconds seconds
The status information of a completed task is automatically removed after being queried with tasks status or tasks tree
tasks wait returns the status, but it does not remove the task information of the queried task
Note
Multiple status queries using tasks status and tasks tree for the same completed task will only receive a response for the first query, since the status is removed after being retrieved.
