-Rich functions provide, in addition to the user-defined function (map,
-reduce, etc), four methods: `open`, `close`, `getRuntimeContext`, and
-`setRuntimeContext`. These are useful for parameterizing the function
-(see [Passing Parameters to Functions]({{ site.baseurl

-creating and finalizing local state, accessing broadcast variables (see

-information such as accumulators and counters (see
