> It the example TableProvider may know that it needed to provide only last record batch (or the latest parquet file from folder). The provider can tell DataFusion it produces data in some pre-existing order via https://docs.rs/datafusion/latest/datafusion/physical_plan/trait.ExecutionPlan.html#tymethod.properties which can then communicate the sortedness via https://docs.rs/datafusion/latest/datafusion/physical_plan/struct.PlanProperties.html#method.output_ordering However, that usecase is for data that is already always sorted. It doesn't permit DataFusion to say "I won't use the sort order you reported so you don't have to honor the contract" 🤔 -- This is an automated message from the Apache Git Service.
