abstract class DataCommitter[A <: DataFlow[A]] extends AnyRef

Defines phases of each data committers in the data flow, which are: 1) validate that committer is properly configured 2) cache the labels in temp area 3) when flow is successful, move all cached data into its permanent storage 4) finalise or cleanup after the committer had committed all of the data into permanent storage
