Their specifics are determined as they are added to "coordinated task", 
I am sure we can tune this to requirements we need.

|CacheManager cm = ...;
CoordinatedTask task = cm.newCoordinatedTask("finalOutcomeCacheName");
cm.addLocalTask(*new*  GridFileQuery("my_gridfs"));// Fetch
cm.addLocalTask(*new*  GridFileSizeCounter());// Map
cm.addGlobalTask(*new*  IntegerSummarizer("my_gridfs_size");// Reduce|
