> You can request that a compaction be started, but you can't be sure when that
> compaction request completes. This is a simple update to the
> CompactionRequest interface and the compact-split thread on the RS that
> doesn't actually impact the RS exposed interface.
> This is particularly useful for CPs so they can control starting/running a
> compaction.
> *Update - Better description (3/20/13):*
> Enable coprocessors to submit custom compaction requests.
> This compaction request is used (if not null) through the entire compaction
> process. If no custom compaction request is submitted (its null - the normal
> case) then we we build a new compaction request via the usual mechanisms in
> the Store.
> Adding this mechanism is particularly useful when 'special' compactions are
> desired and you want to do things like: only change certain files for a
> particularly requested compaction or follow a single compaction through the
> queue.
