Subject [jira] [Created] (CASSANDRA-13187) Allow Filtering on Cluster Key columns while Partition Key is given
Date Mon, 06 Feb 2017 22:50:41 GMT
Srini created CASSANDRA-13187:
---------------------------------

             Summary: Allow Filtering on Cluster Key columns while Partition Key is given
                 Key: CASSANDRA-13187
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13187
             Project: Cassandra
          Issue Type: Bug
          Components: CQL
            Reporter: Srini
             Fix For: 3.0.8


create table table1 (
      k_part_one text,
      k_part_two int,
      k_clust_one text,
      k_clust_two int,
      k_clust_three uuid,
      data1 text,
      data2 text,
      PRIMARY KEY((k_part_one,k_part_two), k_clust_one, k_clust_two, k_clust_three)      
  );

select k_clust_one, k_clust_three , data1 
from table1  where k_part_one = ‘xxxxx’ and k_part_two = ‘yyyy’  and k_clust_two =
‘xxxx’ allow filtering;

Allow filtering works on non primary key columns but it doesn't work on clustering key columns
for a given partition key. The above example  skipped k_clust_one and thus gives an error.

This is very similar to CASSANDRA-6377, CASSANDRA-11310, CASSANDRA -10715. Yet, this is still
unresolved.

This is very critical use case, where we want to avoid sending entire wide row to the client
and do filtering locally. It is an unnecessary network hog that needs be avoided by doing
the filtering on the actual Cassandra node.

Please note that there is no secondary index on this column family..
