Constructor Summary

Constructors

Constructor and Description
SSTableDeletingTask(Descriptor realDescriptor, java.util.Set<Component> components, com.codahale.metrics.Counter totalDiskSpaceUsed, long bytesOnDisk) realDescriptor is the actual descriptor for the sstable, the descriptor inside referent can be 'faked' as FINAL for early opened files.

Method Summary

Modifier and Type	Method and Description
static void	pauseDeletions(boolean stop)
static void	rescheduleFailedTasks() Retry all deletions that failed the first time around (presumably b/c the sstable was still mmap'd.) Useful because there are times when we know GC has been invoked; also exposed as an mbean.
void	run()
static void	waitForDeletions() for tests

Constructor Detail

SSTableDeletingTask

public SSTableDeletingTask(Descriptor realDescriptor,
                           java.util.Set<Component> components,
                           com.codahale.metrics.Counter totalDiskSpaceUsed,
                           long bytesOnDisk)

realDescriptor is the actual descriptor for the sstable, the descriptor inside referent can be 'faked' as FINAL for early opened files. We need the real one to be able to remove the files.
