Method Detail

create

public static ArrayBackedPartition create(UnfilteredRowIterator iterator)

Creates an ArrayBackedPartition holding all the data of the provided iterator. Warning: Note that this method does not close the provided iterator and it is up to the caller to do so.

Parameters:

iterator - the iterator to gather in memory.

Returns:

the created partition.

create

public static ArrayBackedPartition create(UnfilteredRowIterator iterator,
                                          int initialRowCapacity)

Creates an ArrayBackedPartition holding all the data of the provided iterator. Warning: Note that this method does not close the provided iterator and it is up to the caller to do so.

Parameters:

iterator - the iterator to gather in memory.

initialRowCapacity - sizing hint (in rows) to use for the created partition. It should ideally correspond or be a good estimation of the number or rows in iterator.

Returns:

the created partition.

canHaveShadowedData

protected boolean canHaveShadowedData()

Specified by:

canHaveShadowedData in class AbstractThreadUnsafePartition

staticRow

public Row staticRow()

Specified by:

staticRow in class AbstractThreadUnsafePartition

deletionInfo

public DeletionInfo deletionInfo()

Description copied from class: AbstractThreadUnsafePartition

The deletion info for the partition update. Note: do not cast the result to a MutableDeletionInfo to modify it!

Specified by:

deletionInfo in class AbstractThreadUnsafePartition

Returns:

the deletion info for the partition update for use as read-only.

stats
