Method Detail

create

public static ImmutableBTreePartition create(UnfilteredRowIterator iterator)

Creates an ImmutableBTreePartition 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 ImmutableBTreePartition create(UnfilteredRowIterator iterator,
                                             boolean ordered)

Creates an ImmutableBTreePartition 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.

ordered - true if the iterator will return the rows in order, false otherwise.

Returns:

the created partition.

create

public static ImmutableBTreePartition create(UnfilteredRowIterator iterator,
                                             int initialRowCapacity)

Creates an ImmutableBTreePartition 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.

create

public static ImmutableBTreePartition create(UnfilteredRowIterator iterator,
                                             int initialRowCapacity,
                                             boolean ordered)

Creates an ImmutableBTreePartition 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.

ordered - true if the iterator will return the rows in order, false otherwise.

Returns:

the created partition.
