Subject [jira] [Created] (CASSANDRA-8720) Provide tools for finding wide row/partition keys
Date Mon, 02 Feb 2015 21:49:34 GMT
J.B. Langston created CASSANDRA-8720:

             Summary: Provide tools for finding wide row/partition keys
                 Key: CASSANDRA-8720
             Project: Cassandra
          Issue Type: Improvement
            Reporter: J.B. Langston

Multiple users have requested some sort of tool to help identify wide row keys. They get into
a situation where they know a wide row/partition has been inserted and it's causing problems
for them but they have no idea what the row key is in order to remove it.  

Maintaining the widest row key currently encountered and displaying it in cfstats would be
one possible approach.

Another would be an offline tool (possibly an enhancement to sstablekeys) to show the number
of columns/bytes per key in each sstable. If a tool to aggregate the information at a CF-level
could be provided that would be a bonus, but it shouldn't be too hard to write a script wrapper
to aggregate them if not.
