Interface ScrubPartitionIterator

All Superinterfaces:
AutoCloseable, Closeable
All Known Implementing Classes:
ScrubIterator
public interface ScrubPartitionIterator extends Closeable
Iterator over the partitions of an sstable used for scrubbing.

The difference between this and PartitionIterator is that this only uses information present in the index file and does not try to read keys of the data file (for the trie index format), thus key() can be null.

Starts advanced to a position, advance() is to be used to go to next, and iteration completes when dataPosition() == -1.
