How to access results from Map step in MapReduce job?

I am trying to write a MapReduce job without a reduce step - I would like to directly access the results from the map step. What is the best way to accomplish this?

If you want to access the data immediately, there is a type called MapResult that contains the results. To access the data, try something along the lines of:

var objs = MapResult.fetch({filter: 'runIdAndOutKey=="THE_KEY_OF_THE_MAP_RESULTS"', limit:-1})

That being said, if you want to have access to the data longer-term, it is recommended to persist/store the data. For example, by having the map step upsert the results.
