----------------------------------------
Summary: Query in reversed order brough back deleted data
Key: CASSANDRA-12659
URL: https://issues.apache.org/jira/browse/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
{noformat}
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;
{noformat}
Query are doing reverse order on column timestamp
Ex:
{noformat}
select * from data where uid="uid1" order by version DESC
{noformat}
