package workflow
A Workflow is a graph of atomic operations, with WorkflowOps for the vertices.
A Workflow is a graph of atomic operations, with WorkflowOps for the vertices. We crush them down into a WorkflowTask. This crush gives us a location to optimize our workflow decisions. EG, A sequence of simple ops may be combined into a single pipeline request, but if one of those operations contains JS, we have to execute that outside of a pipeline, possibly reordering the other operations to avoid having two pipelines with a JS operation in the middle.
We also implement the optimizations atomic http://docs.mongodb.org/manual/core/aggregation-pipeline-optimization/ so that we can build others potentially on top of them (including reordering non-pipelines around pipelines, etc.).

PipelineOp

Companion object PipelineOp

final case class PipelineOp(op: WorkflowF[slamdata.Predef.Unit], bson: Doc) extends Product with Serializable

A "newtype" for ops that appear in pipelines, for use mostly after a workflow is constructed, with fixed type that can represent any workflow.
