> A metric that indicates how many of the scan requests were without start row and/or stop
row. Generally such queries may be wrongly written or may require better schema design and
those may be some queries doing some sanity check to verify if their actual application logic
has done the necessary updates and the all that expected rows are processed. 
> We do have some logs at the RPC layer to see what queries take time but nothing as a
metric.
