> I am a bit confused about the usage of compareFn here. State is per key, so I believe that your DoFn will only join items that have the same key - the compareFn will never even get to compare items with different keys. Is the idea to allow the user to generate a subset of an equijoin? Yes, it will be a subset of an equijoin.
