Module mz_dataflow_types::plan
source · [−]Expand description
An explicit representation of a rendering plan for provided dataflows.
Modules
Planning of Plan::Join
operators, and supporting types.
Nested message and enum types in ProtoGetPlan
.
Nested message and enum types in ProtoPlan
.
Reduction execution planning and dataflow construction.
We build ReducePlan
s 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
.
Various bits of state to print along with error messages during LIR planning, to aid debugging.
Enums
How a Get
stage will be rendered.
A rendering plan with as much conditional logic as possible removed.
Constants
Functions
A strategy that produces arrangements that are thinner than the default. That is the number of direct children is limited to a maximum of 3.
Helper method to convert linear operators to MapFilterProject instances.
