ConstantIndexer always puts the item on a single channel.

Batch is an aggregate of points for a particular data system.

BatchFactory returns a new empty batch for storing points.

Benchmark is an interface that represents the skeleton of a program needed to run an insert or load benchmark.

DBCreator is an interface for a benchmark to do the initial setup of a database in preparation for running a benchmark against it.

DBCreatorCloser is a DBCreator that also needs a Close method to cleanup any connections after the benchmark is finished.

DBCreatorPost is a DBCreator that also needs to do some initialization after the database is created (e.g., only one client should actually create the DB, so non-creator clients should still set themselves up for writing).

PointIndexer determines the index of the Batch (and subsequently the channel) that a particular point belongs to.

Processor is a type that processes the work for a loading worker.

ProcessorCloser is a Processor that also needs to close or cleanup afterwards.
