EnvDoFn

trait EnvDoFn[A, B, E] extends DoFunction

Interface for specifying parallel operation over DLists. The semantics of DoFn lifecycle are as follows:

For a given chunk of DList elements: 1. 'setup' will be called; 2. 'process' will be called for each element in the chunk; 3. 'cleanup' will be called.

These 3 steps encapsulate the entire life-cycle of a DoFn. A DoFn object will not be referenced after these steps
