• requestCompaction

  List<CompactionRequest> requestCompaction(Region r,
                                          String why)
                                            throws IOException

  Parameters:

  r - Region to compact

  why - Why compaction was requested -- used in debug messages

  Returns:

  The created CompactionRequests or an empty list if no compactions were started

  Throws:

  IOException

  List<CompactionRequest> requestCompaction(Region r,
                                          String why,
                                          List<Pair<CompactionRequest,Store>> requests)
                                            throws IOException

  Parameters:

  r - Region to compact

  why - Why compaction was requested -- used in debug messages

  requests - custom compaction requests. Each compaction must specify the store on which it is acting. Can be null in which case a compaction will be attempted on all stores for the region.

  s - Store within region to compact

  why - Why compaction was requested -- used in debug messages

  request - custom compaction request for the Region and Store. Custom request must be null or be constructed with matching region and store.
