   Just went over the code, and we are actually using the proper metadata push 
API (the other way is letting the controller download the segment and extract 
the metadata). The inefficiency comes from not using the metadata from the 
local generated segment.
   Ideally, we should follow these steps when generating and pushing the 
segments:
   1. Generate the segments from the raw data
   2. Cache the segment metadata from the local files
   3. Tar the segments and upload to deep store
   4. Push segments using the cached metadata
