Type Members

  1. case class JoinConditionSplitPredicates(leftSideOnly: Option[Expression], rightSideOnly: Option[Expression], bothSides: Option[Expression], full: Option[Expression]) extends Product with Serializable

    Wrapper around various useful splits of the join condition.

    Wrapper around various useful splits of the join condition. left AND right AND joined is equivalent to full.

    Note that left and right do not necessarily contain *all* conjuncts which satisfy their condition.

    leftSideOnly

    Deterministic conjuncts which reference only the left side of the join.

    rightSideOnly

    Deterministic conjuncts which reference only the right side of the join.

    bothSides

    Conjuncts which are nondeterministic, occur after a nondeterministic conjunct, or reference both left and right sides of the join.

    full

    The full join condition.

  2. sealed trait JoinSide extends AnyRef
  3. case class JoinStateKeyWatermarkPredicate(expr: Expression) extends JoinStateWatermarkPredicate with Product with Serializable

    Predicate for watermark on state keys

  4. case class JoinStateValueWatermarkPredicate(expr: Expression) extends JoinStateWatermarkPredicate with Product with Serializable

    Predicate for watermark on state values

  5. sealed trait JoinStateWatermarkPredicate extends AnyRef
  6. case class JoinStateWatermarkPredicates(left: Option[JoinStateWatermarkPredicate] = None, right: Option[JoinStateWatermarkPredicate] = None) extends Product with Serializable
  7. implicit class StateStoreAwareZipPartitionsHelper[T] extends AnyRef
  8. class StateStoreAwareZipPartitionsRDD[A, B, V] extends ZippedPartitionsBaseRDD[V]

    A custom RDD that allows partitions to be "zipped" together, while ensuring the tasks' preferred location is based on which executors have the required join state stores already loaded.

    A custom RDD that allows partitions to be "zipped" together, while ensuring the tasks' preferred location is based on which executors have the required join state stores already loaded. This class is a variant of org.apache.spark.rdd.ZippedPartitionsRDD2 which only changes signature of f.
