/**
*
* This script is to experiment with a compound shard key.
*
* Goals:
*  1. the hash (h) to always be the same for the same date (down to the day level)
*  2. documents with the same exact date (dMy) go on the same shard but different day to different shards
*  3. will work well with 100m+ documents
*  4. small overhead related to a simple (non-compound) date shard key
*  5. still support targeted queries (as long as "h" field is included in the query by the application)
