[~bschoeni] something for you to take a look at? This would be very nice to
have. We might create a PR and all the discussion would be done there.

> As a follow up to CASSANDRA-12403, it would be very helpful to have a tool to
> process the slow queries that are logged. In the MySQL world, there's a tool
> called mysqldumpslow, which processes a slow query log, abstracts the
> parameters to prepared statements, and shows the queries which are causing
> problems based on frequency. The {{mysqldumpslow}} utillity shows an
> aggregated count & time statistics spent on slow queries. For instance:
> {code}shell> mysqldumpslow
> Reading mysql slow query log from
> /usr/local/mysql/data/mysqld51-apple-slow.log
> Count: 1 Time=4.32s (4s) Lock=0.00s (0s) Rows=0.0 (0), root[root]@localhost
> insert into t2 select * from t1
> Count: 3 Time=2.53s (7s) Lock=0.00s (0s) Rows=0.0 (0), root[root]@localhost
> insert into t2 select * from t1 limit N
> Count: 3 Time=2.13s (6s) Lock=0.00s (0s) Rows=0.0 (0), root[root]@localhost
> insert into t1 select * from t1{code}
