-------------------------------------------

bq.  keeping histograms on each prepared statement could give us

Is the main difference stats on how the query performed?  If so what stats?

>  Add histogram to prepared statements and expose as virtual table

> One of the biggest challenges as an operator is understanding what queries 
> are being executed and how long they take.  We have the ability to take short 
> samples via profileload, but it’s lacking the full diagnostics that keeping 
> histograms on each prepared statement could give us.  Having this would be a 
> massive benefit to most operators as they currently have no idea what 
> Cassandra is actually doing.
> Before committing let’s be sure to record some CPU flame graphs to ensure 
> there isn’t noticeable performance overhead.
