Subject [jira] [Commented] (CASSANDRA-3143) Global caches (key/row)
Date Wed, 14 Dec 2011 20:17:31 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13169658#comment-13169658
] 

Sylvain Lebresne commented on CASSANDRA-3143:
---------------------------------------------

bq. hat is why I'm saying that if we will use metadata.cfId we would cache 2L CFs without
even noticing

Sorry, I was probably not clear. I really just meant replacing the two calls to {{Schema.instance.getId()}}
by {{metadata.cfId}}. We would still have the next line be {{if (cfId == null) return; }}
to avoid caching 2ndary indexes.

> Caches are difficult to configure well as ColumnFamilies are added, similar to how memtables
were difficult pre-CASSANDRA-2006.
