Type Members

  1. trait ArrowAggregate extends Result

    Trait for aggregating arrow files

  2. abstract class ArrowResultsToFeatures[T] extends ResultsToFeatures[T]

    Converts arrow-encoded results to features

    Converts arrow-encoded results to features

    T

    result type

  3. case class ArrowScanConfig(config: Map[String, String], reduce: FeatureReducer) extends Product with Serializable
  4. class DeltaAggregate extends ArrowAggregate

    Returns batches of [threading key][dictionary deltas][record batch].

    Returns batches of [threading key][dictionary deltas][record batch]. Will sort each batch, but not between batches.

  5. class DeltaReducer extends FeatureReducer

    Reduce function for delta batches.

    Reduce function for delta batches.

    First feature contains metadata for arrow file and dictionary batch, subsequent features contain record batches, final feature contains EOF indicator
