   This Jupyter notebook describes what monoids are and the role they play in reduction and aggregation in Spark, specifically PySpark. To illustrate the use of the monoid concept, the following examples are included:

   - Sets as monoids
   - A HyperLogLog monoid (a "sketch method" for approximating set cardinality). NOTE: Uses the implementation, hll.py at https://github.com/Parsely/probably, which has been modified here to remove the dependency on the "smhasher" module and so that it can be run using the Anaconda Python distribution.
