Module dataflow_types::plan [−][src]
Expand description
An explicit representation of a rendering plan for provided dataflows.
Modules
Planning of Plan::Join operators, and supporting types.
Reduction execution planning and dataflow construction.
We build ReducePlans to manage the complexity of planning the generated dataflow for a
given reduce expression. The intent here is that each creating a ReducePlan should capture
all of the decision making about what kind of dataflow do we need to render and what each
operator needs to do, and then actually rendering the plan can be a relatively simple application
of (as much as possible) straight line code.
Threshold planning logic.
TopK planning logic.
Structs
The forms in which an operator’s output is available;
it can be considered the plan-time equivalent of
render::context::CollectionBundle.
Enums
A rendering plan with as much conditional logic as possible removed.
Functions
Helper method to convert linear operators to MapFilterProject instances.
