> The proposal would be to add the following metrics:
> 1. Compaction I/O rate (MB/sec) across all threads (read+write)
> 2. Data size on disk per partition
> 3. Max dirty ratio across all logs
> 4. Max buffer use from all compactions so far
> 5. Survivorship ratio (# records recopied / total records)
