Have the tests do operations in parallel to stress that better, remove some println's from the code
Use an array buffer rather than list buffer for the map sum
Simple keep a mutable map around, synchronizing access
Geeking out to get the performance higher
Benchmark for the Async summers
Keeping the notion of lazily calculated heavy hitters, but fixing it to actually be a lazy val
Add better to string
Silly bug re-using an iterator.
tentative sumOption for EventuallySemiGroup
EventuallyMonoid sumOption tests
Add a helper function to build sketch maps since they have the embedded function now
rename type parameters and update doc to improve readability
Pass the params in, seems to be the more popular approach.
add batching to avoid materializing input in memory
Remove the heavy hitters from the Case class, but remove the other cached usages too. Users can access heavy hitters as a one time call to heavyHitters with no caching, or request the frequencyWithHHCache if they expect to do the lookups often
fix batching; add tests
cleanup
Bad implicit left in place
