Subject [jira] [Updated] (CASSANDRA-7625) cqlsh not paging results
Date Fri, 25 Jul 2014 19:58:39 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-7625?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tyler Hobbs updated CASSANDRA-7625:
-----------------------------------

    Attachment: 7625.txt

7625.txt (and [branch|https://github.com/thobbs/cassandra/tree/CASSANDRA-7625]) always converts
the result to a list in order to handle paged results.

(While it would be nice if cqlsh actually utilized the paging instead of converting everything
to a list, the formatting code requires knowing the max length of values in the results up
front.  At least with paged results, only cqlsh will suffer instead of the coordinator node.)

> If you try to make a selection of more data than can fit in a page, you'll get this error:

> cqlsh> select * from "Keyspace1"."Standard1";
> 'PagedResult' object does not support indexing
> {code}
> With debugging on, I get this traceback:

> Placing a limit on the query still works.
