Would this help? from the docs:
"'Add transaction' support allows constructing object's value on the fly
  without serializing it into a temporary buffer (aka 'zero-copy').
  Uncommited transaction can be rolled back at any time.
  Think of videos streamed directly into the cache without usage of temporary
  buffers or complex objects requiring serialization from multiple distinct
  places before storing them into the cache"

I haven't looked at the code yet.
