Module datafusion::physical_optimizer::pipeline_checker

The PipelineChecker rule ensures that a given plan can accommodate its infinite sources, if there are any. It will reject non-runnable query plans that use pipeline-breaking operators on infinite input(s).

Structs

• PipelineChecker
  The PipelineChecker rule rejects non-runnable query plans that use pipeline-breaking operators on infinite input(s).
• PipelineStatePropagator

Functions

• check_finiteness_requirements
  This function propagates finiteness information and rejects any plan with pipeline-breaking operators acting on infinite inputs.
