Method import_view_into_dataflow

src/adapter/src/optimize/dataflows.rs:394–406

Imports the view with the specified ID and expression into the provided dataflow description. [`OptimizerFeatures`] is used while running expression [`mz_transform::analysis::Analysis`]. You should generally prefer calling [`DataflowBuilder::import_into_dataflow`], which can handle objects of any type as long as they exist in the catalog. This method exists for when the view does not exist in the
