Subject [jira] [Commented] (CASSANDRA-5378) Fat Client: No longer works in 1.2
Date Fri, 05 Apr 2013 18:51:17 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13623941#comment-13623941
] 

Carl Yeksigian commented on CASSANDRA-5378:
-------------------------------------------

If we don't have that, we won't be able to validate a query against the row key.

That is, if the schema is:
{code}
CREATE COLUMNFAMILY standard1 ( id ascii PRIMARY KEY , name ascii , value blob ) ;
SELECT * FROM standard1 WHERE id='abc';
{code}

That select statement will not be validated, as no column is indexed, but the row key is.
It'll throw the "No indexed columns present in by-columns clause with Equal operator" exception.

> The current client only example doesn't compile. After doing some updates, the fat client
still won't work, mainly because the schema is not being pushed to the fat client.
> I've made changes to the client to support CQL3 commands, to the ServiceManager to wait
until a migration has completed before starting the client, and to the MigrationManager to
not try to pull schemas from a fat client.
