>
> The original design of the compaction estimator was to only focus on binary
> segments when computing the amount of garbage that can be collected.
> This has a flaw when it runs on systems with external data stores configured
> as there will be almost no binary segments and the estimation will always be
> _0_, no need for compaction.
> The change to include all segments is not big, the _uuids_ bloomfilter is
> already initialized with the total number of segments, and the segment
> collection already loads everything in memory.
