Subject [jira] [Created] (CASSANDRA-12659) Query in reversed order brough back deleted data
Date Fri, 16 Sep 2016 19:24:21 GMT
Tai Khuu Tan created CASSANDRA-12659:

             Summary: Query in reversed order brough back deleted data
                 Key: CASSANDRA-12659
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: Cassandra 3.0.5, 6 nodes cluster
            Reporter: Tai Khuu Tan

We have and issues with our Cassandra 3.0.5. After we deleted a large amount of data in the
multiple partition keys. Query those partition keys with reversed order on a clustering key
return the deleted data. I have checked and there are no tombstones left. All of them are
deleted. So I don't know where or how can those deleted data still exist. Is there any other
place that Cassandra will read data when query in reverse order compare to normal order ?
the schema is very simple

CREATE TABLE table ( uid varchar, version timestamp, data1 varchar, data2 varchar, data3 varchar,
data4 varchar, data5 varchar, PRIMARY KEY (uid, version, data1 , data2 , data3 , data4 ) )
with compact storage;

Query are doing reverse order on column timestamp

select * from data where uid="uid1" order by version DESC
