>
> Sometimes you know you have a hot partition by the load on a replica set, but
> have no way of determining which partition it is. Tracing is inadequate for
> this without a lot of post-tracing analysis that might not yield results.
> Since we already include stream-lib for HLL in compaction metadata, it
> shouldn't be too hard to wire up topK for X seconds via jmx/nodetool and then
> return the top partitions hit.
