>                 Key: CASSANDRA-5672
>                 URL:
>             Project: Cassandra
>          Issue Type: Improvement
>    Affects Versions: 1.2.0
>            Reporter: Ryan McGuire
>            Assignee: Tyler Hobbs
>            Priority: Minor
>             Fix For: 2.1
> Tracing of queries is useful for at least two different purposes:
> * Interactively diagnosing a problem, via cqlsh, by a human.
> * Programatically recording and responding to how queries behave.
> This second purpose is not well suited to how the table is currently
organized, as the only identifying characteristic of each event is a free-form string that
can (and has) been changed in later versions.
> [~jbellis] [mentioned the possibility|]
of adding an enumeration of event types that would be immutable.
> Reference [this dtest|] that
parses the strings in this table via regex. If these strings change, this test will break.
