Subject [jira] [Commented] (CASSANDRA-12003) Not filtering Data completely when where clause is applied to clustering column
Date Tue, 14 Jun 2016 16:41:57 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12003?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15329839#comment-15329839
] 

Eric Stevens commented on CASSANDRA-12003:
------------------------------------------

In the mailing list it looked like you might be using SASI with LIKE-style queries ({{WHERE
id=2134 AND col1 = '\*value\*'}}), is that the case?  If so it looks like your schema and
example case might be incomplete here, so more details would be helpful.

> On issuing this query:;
> select id,col1 from table where id=2134 and col1='clust_key1';
>  id   | col1
> ------+----------------------
>  2429 | clust_key2
>  2429 |                clust_key3
> ------------more rows-------
>  2429 |               clust_key1
> ------------more rows-------
>  2429 |         clust_key4
>  2429 |           clust_key5
> (16 rows)
> Whereas only one result was expected (Row bearing col1 - clust_key1), we got that result
but along with 15 other unexpected rows..
> Total number of rows in the partition are 20 (Verified using select id,col1 from table
where id=2134; ) as well as json dump. We are wondering why Cassandra could not filter the
results completely. I have checked that the data is intact by taking json dump and validating
using sstabledump tool.
