*Review only* APEXCORE-259 Directly write to DataList
Instead of the loop back between the Output port and the buffer server,
tuples are directly written to DataList. This improves the tuples write to
BufferServer, but exposing the bottleneck between downStream and BufferServer,
which in turn mean too much spooling.
This PR along with the following PRs improves the performance to great
extent.
