getScrubber

public IScrubber getScrubber(ColumnFamilyStore cfs,
 LifecycleTransaction transaction,
 OutputHandler outputHandler,
 IScrubber.Options options)

Description copied from interface: SSTableFormat

delete

public void delete(Descriptor desc)

Description copied from interface: SSTableFormat

Deletes the existing components of the sstables represented by the provided descriptor. The method is also responsible for cleaning up the in-memory resources occupied by the stuff related to that sstables, such as row key cache entries.
