Subject [jira] [Commented] (CASSANDRA-8767) "Added column does not sort as the last column" when using new python driver
Date Thu, 12 Feb 2015 16:28:11 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8767?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14318492#comment-14318492

Russ Garrett commented on CASSANDRA-8767:
-----------------------------------------

Fetch size would be the default. The partition sizes are quite variable - usually between
2000 and 20000 cql rows (which are each several hundred bytes in size uncompressed).

> We've just upgraded one of our python apps from using the old cql library to the new
python-driver. When running one particular query, it produces the attached assertion error
in Cassandra. The query is: 
> bq. SELECT buffer, id, type, json FROM events WHERE buffer = %(bid)s AND idkey = %(idkey)s
ORDER BY id ASC
> Where buffer and idkey are integer primary keys, and id is the clustering key (ordered
asc).
> This query, with identical parameters, does not cause this error using the old cql python
library, or with the cqlsh client..
