| synchronized boolean | addPendingDB(DatabaseId dbId)
Adds the given DatabaseId to the pending DB set. |
| synchronized boolean | addPendingLN(LN ln, DatabaseId dbId, byte[] key, byte[] dupKey)
Adds the given LN info to the pending LN set. |
| synchronized Set | copySafeToDeleteFiles()
Returns a copy of the safe-to-delete files. |
| synchronized int | getBacklog()
Returns the number of files waiting to-be-cleaned. |
| synchronized CheckpointStartCleanerState | getFilesAtCheckpointStart()
Returns a copy of the cleaned and fully-processed files at the time a
checkpoint starts. |
| Set | getLowUtilizationFiles()
Returns a read-only set of low utilization files that can be accessed
without synchronization. |
| synchronized Set | getMustBeCleanedFiles()
Returns a read-only copy of to-be-cleaned and being-cleaned files that
can be accessed without synchronization. |
| synchronized DatabaseId[] | getPendingDBs()
Returns an array of DatabaseIds for DBs that were pending deletion in a
prior cleaning attempt, or null if no DBs are pending. |
| synchronized LNInfo[] | getPendingLNs()
Returns an array of LNInfo for LNs that could not be migrated in a
prior cleaning attempt, or null if no LNs are pending. |
| synchronized boolean | isFileCleaningInProgress(Long file)
Returns whether the file is in any stage of the cleaning process. |
| synchronized void | putBackFileForCleaning(Long fileNum)
When file cleaning is aborted, move the file back from the being-cleaned
set to the to-be-cleaned set. |
| synchronized void | removeAllFileReferences(Long file)
Removes all references to a file. |
| synchronized void | removeDeletedFile(Long fileNum)
Removes file from the safe-to-delete set after the file itself has
finally been deleted. |
| synchronized void | removePendingDB(DatabaseId dbId)
Removes the DatabaseId from the pending DB set. |
| synchronized void | removePendingLN(long nodeId)
Removes the LN for the given node ID from the pending LN set. |
| Long | selectFileForCleaning(UtilizationProfile profile, boolean forceCleaning, boolean calcLowUtilizationFiles, int maxBatchFiles)
Returns the best file that qualifies for cleaning, or null if no file
qualifies. |
| synchronized void | updateFilesAtCheckpointEnd(CheckpointStartCleanerState info)
When a checkpoint is complete, move the previously cleaned and
fully-processed files to the checkpointed and safe-to-delete sets. |
