Method Detail

getOnlyElement

public static RowIterator getOnlyElement(PartitionIterator iter,
                                         SinglePartitionReadCommand command)

concat

public static PartitionIterator concat(java.util.List<PartitionIterator> iterators)

digest

public static void digest(PartitionIterator iterator,
                          java.security.MessageDigest digest)

singletonIterator

public static PartitionIterator singletonIterator(RowIterator iterator)

consume

public static void consume(PartitionIterator iterator)

loggingIterator

public static PartitionIterator loggingIterator(PartitionIterator iterator,
                                                java.lang.String id)

Wraps the provided iterator so it logs the returned rows for debugging purposes.

Note that this is only meant for debugging as this can log a very large amount of logging at INFO.
