The unassignTasks() GraphQL mutation may
be used to unassign node tasks. It returns the set of assigned tasks
after the unassign operation has completed.
For more information on common node tasks, see the
LogScale Logical Architecture page in the Training
section.
Below is the syntax for the
unassignTasks() mutation field:
unassignTasks(
nodeID : integer!
tasks : [ NodeTaskEnum! ] !
) : [ NodeTaskEnum! ] !
Below is an example of how this mutation field might be used:
