> Multiple users have requested some sort of tool to help identify wide row 
> keys. They get into a situation where they know a wide row/partition has been 
> inserted and it's causing problems for them but they have no idea what the 
> row key is in order to remove it.  
> Maintaining the widest row key currently encountered and displaying it in 
> cfstats would be one possible approach.
> Another would be an offline tool (possibly an enhancement to sstablekeys) to 
> show the number of columns/bytes per key in each sstable. If a tool to 
> aggregate the information at a CF-level could be provided that would be a 
> bonus, but it shouldn't be too hard to write a script wrapper to aggregate 
> them if not.
