[jira] [Updated] (CASSANDRA-7910) wildcard prepared statements are incorrect after a column is added to the table

["Tyler Hobbs (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-7910?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tyler Hobbs updated CASSANDRA-7910:
-----------------------------------
    Attachment: 7910-trunk.txt
                7910-2.1.txt

The attached patches invalidate any prepared statements that deal with the affected table whenever columns are added, dropped, or altered.  The 2.1 patch also backports a minor refactor of IMigrationListener from trunk.

I've pushed a [dtest branch|https://github.com/thobbs/cassandra-dtest/tree/CASSANDRA-7910] as well.

> 3. execute the prepared statement
