> Currently, the compaction selection is not very flexible and is not sensitive
> to the hotness of the data. Very old data is likely to be accessed less, and
> very recent data is likely to be in the block cache. Both of these
> considerations make it inefficient to compact these files as aggressively as
> other files. In some use-cases, the access-pattern is particularly obvious
> even though there is no way to control the compaction algorithm in those
> cases.
> In the new compaction selection algorithm, we plan to divide the candidate
> files into different levels according to oldness of the data that is present
> in those files. For each level, parameters like compaction ratio, minimum
> number of store-files in each compaction may be different. Number of levels,
> time-ranges, and parameters for each level will be configurable online on a
> per-column family basis.
