Subject [jira] [Commented] (TAJO-711) Add Avro storage support
Date Mon, 14 Apr 2014 03:51:15 GMT

    [ https://issues.apache.org/jira/browse/TAJO-711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13968046#comment-13968046

David Chen commented on TAJO-711:

Hi Hyunsik,

Sorry for the delay. I have been a bit busy this week. I have updated the tests to also test
avro.schema.url, and the tests pass. I think this patch is ready to be committed now.

Thanks for opening the ticket. I agree that we may want to store partition entries in the
catalog as well. From what I understand, Hive currently does this and is how it handles this
kind of schema evolution.

I'm interesting in learning more about your idea for the table to explicitly support schema
evolution. Can you elaborate on how that would work?
