-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
}}/dev/batch/index.html#passing-parameters-to-functions)),
-creating and finalizing local state, accessing broadcast variables (see
-[Broadcast Variables]({{ site.baseurl

-information such as accumulators and counters (see
-[Accumulators and Counters](#accumulators--counters)), and information
-on iterations (see [Iterations]({{ site.baseurl }}/dev/batch/iterations.html)).
