Subject [jira] [Commented] (CASSANDRA-10155) 2i key cache load fails
Date Fri, 11 Sep 2015 12:18:45 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14740686#comment-14740686

Robert Stupp commented on CASSANDRA-10155:
------------------------------------------

Fair enough - let's stick with the {{Pair}} then. And with {{ksAndCFName}} unless someone
else has a neat idea.

> CASSANDRA-9265 changed how key cache content is serialized to disk. It uses {{UUID cfId}}
to generate the file path for each {{ColumnFamilyStore}}.
> Since {{cfId}} of a secondary index is the same as for the base table, the key-cache
files for 2i's and the base are the same. This will/may lead to deserialization failures on
restart for tables with at least one 2i.
