pub fn compile_transforms_columnar(
specs: &[TransformSpec],
) -> CliResult<(Vec<TransformStage>, Vec<Option<PageFnBatchBox>>)>Available on crate feature
arrow only.Expand description
Like compile_transforms but also returns each stage’s Arrow
RecordBatch form (parallel to the stages), so the executor can build a
columnar-capable TransformingSource (#375). Only the sql transform
supplies a batch form today; every other stage’s entry is None, which
keeps the whole chain on the Value path unless every stage is columnar.
