When deploying a query the latest PR for HPCC-25845 associates the meta data with the default storage plane for the target roxie. That means that roxie will copy the data once it is referenced.
There may be multiple storage planes that are suitable for the data reside, and the system should not need to copy the files if it is already on a suitable plane.
The roxie config should be extended to have a list of acceptable storagePlanes, and if the data already exists there it should not be cloned.
