RapidsShuffleIterator

class RapidsShuffleIterator extends Iterator[ColumnarBatch] with Logging with Arm

An Iterator over columnar batches that fetches blocks using RapidsShuffleClients.

A transport instance is used to make RapidsShuffleClients that are able to fetch blocks.

Type Members

  1. case class BlockIdMapIndex(id: ShuffleBlockBatchId, mapIndex: Int) extends Product with Serializable
  2. case class BufferReceived(bufferId: ShuffleReceivedBufferId) extends ShuffleClientResult with Product with Serializable

    A result for a successful buffer received

    bufferId

    - the shuffle received buffer id as tracked in the catalog

  3. class GroupedIterator[B >: A] extends AbstractIterator[Seq[B]] with Iterator[Seq[B]]
    Definition Classes
    Iterator
  4. trait ShuffleClientResult extends AnyRef

    General trait encapsulating either a buffer or an error.

    General trait encapsulating either a buffer or an error. Used to hand off batches to tasks (in the good case), or exceptions (in the bad case)

  5. case class TransferError(blockManagerId: BlockManagerId, blockId: ShuffleBlockBatchId, mapIndex: Int, errorMessage: String, throwable: Throwable) extends ShuffleClientResult with Product with Serializable

    A result for a failed attempt at receiving block metadata, or corresponding batches.

    A result for a failed attempt at receiving block metadata, or corresponding batches.

    blockManagerId

    - the offending peer block manager id

    blockId

    - shuffle block id that we were fetching

    mapIndex

    - the mapIndex (as returned by the MapOutputTracker in blocksByAddress

    errorMessage

    - a human-friendly error to report
