Subject [jira] Commented: (HADOOP-6660) add Writable wrapper for Avro data
Date Thu, 25 Mar 2010 20:05:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6660?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12849876#action_12849876
] 

Zheng Shao commented on HADOOP-6660:
------------------------------------

How does the Writable class get the metadata (like type information)?
Are we going to serialize metadata with data for each key(or value)? That will be a loss of
efficiency.
