Subject [jira] [Created] (CASSANDRA-9149) nodes slow down when having too many column families

ZhaoYang created CASSANDRA-9149:
-----------------------------------

             Summary: nodes slow down when having too many column families
                 Key: CASSANDRA-9149
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9149
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: ZhaoYang


When creating a few thousand column families, the nodes(2-3) slow down a lot.  In my case,
the number of column families will continue increase. 
Currently, some advice is like modeling(*hacking*) data to fit in smaller number of column
families. But this method really didn't work well due to lack of atomicity and bad performance.
 
Is there a way to solve it or improve it in future release? It's okay to make the cluster
a bit slower, as long as not too slow. Any suggestions are welcome.
