Nitin, If we provide any APIs for the staging/temporary area, they must be read-only. Allowing any external manipulation of its content could cause break in-flight transfers or cause data loss. I think we should consider the following APIs:
List contents including name, reference count, and size Summary statistics for a staging area including consumed/available/total space and timestamp of the last garbage collection operation Force garbage collection/cleanup operation I think we should these are new API calls specific to the staging/temporary area mechanism rather than trying to overload existing API calls.
