Method Detail

getPurgeEvaluator

protected abstract java.util.function.LongPredicate getPurgeEvaluator()

onNewPartition

protected void onNewPartition(DecoratedKey partitionKey)

onEmptyPartitionPostPurge

protected void onEmptyPartitionPostPurge(DecoratedKey partitionKey)

updateProgress

protected void updateProgress()

setReverseOrder

protected void setReverseOrder(boolean isReverseOrder)

applyToPartition

protected UnfilteredRowIterator applyToPartition(UnfilteredRowIterator partition)

Description copied from class: Transformation

Applied to any rows iterator (partition) we encounter in a partitions iterator

Overrides:

applyToPartition in class Transformation<UnfilteredRowIterator>

applyToDeletion

protected DeletionTime applyToDeletion(DeletionTime deletionTime)

Description copied from class: Transformation

Applied to the partition-level deletion of any rows iterator. NOTE that this is only applied to the first iterator in any sequence of iterators filled by a MoreContents; the static data for such iterators is all expected to be equal

Overrides:

applyToDeletion in class Transformation<UnfilteredRowIterator>

applyToStatic

protected Row applyToStatic(Row row)

Description copied from class: Transformation

Applied to the static row of any rows iterator. NOTE that this is only applied to the first iterator in any sequence of iterators filled by a MoreContents; the static data for such iterators is all expected to be equal

Overrides:

applyToStatic in class Transformation<UnfilteredRowIterator>

applyToRow

protected Row applyToRow(Row row)

Description copied from class: Transformation

Applied to any row we encounter in a rows iterator

Overrides:

applyToRow in class Transformation<UnfilteredRowIterator>

applyToMarker

protected RangeTombstoneMarker applyToMarker(RangeTombstoneMarker marker)

Description copied from class: Transformation

Applied to any RTM we encounter in a rows/unfiltered iterator

Overrides:

applyToMarker in class Transformation<UnfilteredRowIterator>
