> To identify causes of load on a cluster, it would be useful to have some additional metrics:
> * *Mutation size distribution:* I believe this would be relevant when tracking the performance
of unlogged batches.
> * *Logged / Unlogged Partitions per batch distribution:* This would also give a count
of batch types processed. Multiple distinct tables in batch would just be considered as separate
partitions.
