Subject [jira] [Commented] (CASSANDRA-8216) Select Count with Limit returns wrong value
Date Thu, 08 Oct 2015 12:41:26 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14948599#comment-14948599
] 

Benjamin Lerer commented on CASSANDRA-8216:
-------------------------------------------

I completly agree that I should have put an entry in the {{NEWS.txt}}.

To be honest, I forgot that I had changed the behaviour.
When [~aholmber] reported CASSANDRA-10380, I tested {{2.2}} and found out the same behavior
than {{2.1}}. I concluded wrongly that the change was coming from CASSANDRA-8099 ([~slebresne]
you were right as always).

Now, the problem is that, after I changed the code, another change caused the code to revert
to the old behavior. I have not found which one yet but it impact only {{2.2}}. So I need
to fix that issue and backport the CASSANDRA-10380 change to {{2.2}}.

> The dtest cql_tests.py:TestCQL.select_count_paging_test is failing on trunk HEAD but
not 2.1-HEAD.
> The query {code} select count(*) from test where field3 = false limit 1; {code} is returning
2, where obviously it should only return 1 because of the limit. This may end up having the
same root cause of #8214, I will be bisecting them both soon.
