[jira] [Updated] (CASSANDRA-9913) Select * is only returning the
first page of data on trunk
[ https://issues.apache.org/jira/browse/CASSANDRA-9913?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Benjamin Lerer updated CASSANDRA-9913:
--------------------------------------
Component/s: CQL
> Select * is only returning the first page of data on trunk
> ----------------------------------------------------------
>
> Key: CASSANDRA-9913
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9913
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Reporter: Philip Thompson
> Assignee: Benjamin Lerer
> Fix For: 3.0 beta 1
>
> Attachments: 9913.txt
>
>
> While doing some testing on the validation harness, I have run into a pretty trivially reproducible problem.
> {code}
> ccm create test -v git:trunk -n 1 -s
> ccm node1 stress write n=2M
> ccm node1 cqlsh
> {code}
> {code}
> Use keyspace1;
> Select * From standard1; (100 rows)
> Select count(*) from standard1; (300 rows)
> {code}
> Despite two million rows being written, I have found that {{select * from standard1}} only returns one page's worth of data. I have used both the java and the python driver to test this. I have also found that {{select count(*) from standard1}} gives a multiple of one page's worth of data, that appears to correspond to page size * RF.
> I have already tried with the patch for CASSANDRA-9775, and that did not resolve this issue.
