      Description

      I just noticed this strange output in the coordinator_reads output::

      cqlsh:system_views> select * from coordinator_reads ;
      
       count | keyspace_name      | table_name                     | 99th | max | median | per_second
      -------+--------------------+--------------------------------+------+-----+--------+------------
        7573 |         tlp_stress |                       keyvalue |    0 |   0 |      0 | 2.2375e-16

      btw I realize the output is technically correct, but it's not very readable. For practical purposes this should just say 0.
