Subject [jira] [Created] (CASSANDRA-3469) More fine-grained request statistics
Date Tue, 08 Nov 2011 03:06:53 GMT
More fine-grained request statistics
------------------------------------

                 Key: CASSANDRA-3469
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3469
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
            Reporter: Jonathan Ellis
            Assignee: Yuki Morishita
            Priority: Minor
             Fix For: 1.1


It would be useful to split the CFS stats up by query type.  slice vs named vs range vs index,
to start with (right now we don't track range scans at all), but also at the "prepared statement"
level as it were:

{{{SELECT x FROM foo WHERE key = ?}}} would be one query no matter what the ? is, but {{{SELECT
y FROM foo WHERE key = ?}}} would be different.  {{{SELECT x..y FROM foo WHERE key = ?}}}
would be another, as would {{{SELECT x FROM foo WHERE key = ? AND bar= ?}}}.  (But {{{SELECT
x FROM foo WHERE bar = ? AND key = ?}}} would be identical to the former, of course.)
