It would be nice to have a haskell library that matches the feature set of the KCL.

Some notable features:
- Checkpoints processed records (handled remotely so tolerant of a machine disappearing)
- Coordinates shard associations with other workers
- Balances shard-worker associations
The way KCL implements this is through a dynamodb table where it keeps track of the current owner/checkpoint and other info in a single row per shard per application
