ObjectHashAggregateExec

case class ObjectHashAggregateExec(requiredChildDistributionExpressions: Option[Seq[Expression]], isStreaming: Boolean, numShufflePartitions: Option[Int], groupingExpressions: Seq[NamedExpression], aggregateExpressions: Seq[AggregateExpression], aggregateAttributes: Seq[Attribute], initialInputBufferOffset: Int, resultExpressions: Seq[NamedExpression], child: SparkPlan) extends SparkPlan with BaseAggregateExec with Product with Serializable

A hash-based aggregate operator that supports TypedImperativeAggregate functions that may use arbitrary JVM objects as aggregation states.

Similar to HashAggregateExec, this operator also falls back to sort-based aggregation when the size of the internal hash map exceeds the threshold. The differences are:

  • It uses safe rows as aggregation buffer since it must support JVM objects as aggregation states.
  • It tracks entry count of the hash map instead of byte size to decide when we should fall back. This is because it's hard to estimate the accurate size of arbitrary JVM objects in a lightweight way.
  • Whenever fallen back to sort-based aggregation, this operator feeds all of the rest input rows into external sorters instead of building more hash map(s) as what HashAggregateExec does. This is because having too many JVM object aggregation states floating there can be dangerous for GC.
  • CodeGen is not supported yet.

This operator may be turned off by setting the following SQL configuration to false:

spark.sql.execution.useObjectHashAggregateExec

The fallback threshold can be configured by tuning:

    Specifies the data distribution requirements of all the children for this operator.

    Specifies the data distribution requirements of all the children for this operator. By default it's UnspecifiedDistribution for each child, which means each child can have any distribution.

    If an operator overwrites this method, and specifies distribution requirements(excluding UnspecifiedDistribution and BroadcastDistribution) for more than one child, Spark guarantees that the outputs of these children will have same number of partitions, so that the operator can safely zip partitions of these children's result RDDs. Some operators can leverage this guarantee to satisfy some interesting requirement, e.g., non-broadcast joins can specify HashClusteredDistribution(a,b) for its left child, and specify HashClusteredDistribution(c,d) for its right child, then it's guaranteed that left and right child are co-partitioned by a,b/c,d, which means tuples of same value are in the partitions of same index, e.g., (a=1,b=2) and (c=1,d=2) are both in the second partition of left and right child.
