@xiaoxmeng : Please can you add a release note documenting this property.

To clarify by default a query can reclaim from another query, but this property restricts arbitration to only look at other tasks of the same query ? Or is it something else ?

By default, this option is off at Velox side. This provides a system config to turn it on in Prestissimo. This doesn't change the behavior of Prestissimo.
