When is ViewMutationStage ever used? I am trying to have a test that will
result in tasks getting executed in this stage to verify metrics for
ViewMutuationStage.
I been going through the code and see in StorageProxy::mutateMV it will

value" . This is quite expensive and will be using quite a lot of I/O to
