Subject [jira] [Commented] (CASSANDRA-5800) Support pre-1.2 release CQL3 tables in CqlPagingRecordReader
Date Fri, 09 Aug 2013 20:24:48 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5800?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13735235#comment-13735235

Tyler Hobbs commented on CASSANDRA-5800:
----------------------------------------

The patch looks good except for a minor nit: I would rename {{upgradeCQL3tables()}} to {{migrateKeyAlias()}},
or something along those lines.

> Pre-1.2 release CQL3 table stores the key in system.schema_columnfamilies key_alias column
which is different from 1.2 release. We should support it in CqlPagingRecordReader as well.
