             Summary: Real time Bad query logging framework
                 Key: CASSANDRA-14527
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14527
             Project: Cassandra
          Issue Type: New Feature
          Components: Observability
            Reporter: Jaydeepkumar Chovatia
            Assignee: Jaydeepkumar Chovatia
             Fix For: 4.0


If Cassandra is not used in right way then it can create adverse effect to the 
application. There are lots of bad queries when using Cassandra, but major 
problem is end user don’t know where and what exactly is the problem. Most of 
the times end user is ready to take actions on bad queries provided Cassandra 
gives all detailed which could have potential impact on cluster performance.

There has been already lots of work done as part of CASSANDRA-12403, proposal 
as part of this JIRA is let’s have some common way of detecting and logging 
different problems in Cassandra cluster which could have potential impact on 
Cassandra cluster performance.

Please visit this document which has details like what is currently available, 
motivation behind developing this common framework, architecture, samples, etc.
