| <div class="block">A memstore implementation which supports in-memory compaction. A compaction pipeline is added |
| between the active set and the snapshot data structures; it consists of a list of segments that |
| are subject to compaction. Like the snapshot, all pipeline segments are read-only; updates only |
| affect the active set. To ensure this property we take advantage of the existing blocking |
| mechanism -- the active set is pushed to the pipeline while holding the region's updatesLock in |
| exclusive mode. Periodically, a compaction is applied in the background to all pipeline segments |
| resulting in a single read-only component. The ``old'' segments are discarded when no scanner is |
| reading them.</div> |
