The setIsBeingEvicted() GraphQL mutation
is used to toggle whether the specified host should be prepared for
eviction from the cluster. If preparing for eviction, the cluster
will attempt to move data and work away from the host.
Below is the syntax for the
setIsBeingEvicted() mutation field:
setIsBeingEvicted(
vhost : integer! ,
isBeingEvicted : boolean!
) : boolean!
Below is an example of how this mutation field might be used:
