Subject [jira] [Commented] (CASSANDRA-12659) Query in reversed order brough back deleted data

Tai Khuu Tan commented on CASSANDRA-12659:
------------------------------------------

[~iamaleksey] I will try to reproduce the issue. Is there anyway we can move the sstable from
1 cluster to another, since the affected cluster is production server it not easy to try different
things on them. I know there is the sstableloader but I don't know if using that will be able
to replicate the sstable?

> 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}
