Subject [jira] [Commented] (CASSANDRA-3966) KeyCacheKey and RowCacheKey to use raw byte[]
Date Tue, 28 Feb 2012 00:37:49 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3966?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13217737#comment-13217737

Vijay commented on CASSANDRA-3966:
----------------------------------

Since i am on this ticket... Wondering if it will make sense to do use FreeableMemory instead
of ByteBuffer if (SerializingCache is chosen) just for RowCacheKey?

> We can just store the raw byte[] instead of byteBuffer,
> After reading the mail
> http://www.mail-archive.com/dev@cassandra.apache.org/msg03725.html
> Each ByteBuffer takes 48 bytes => for house keeping can be removed by just implementing
hashcode and equals in the KeyCacheKey and RowCacheKey
