Subject [jira] Commented: (HIVE-1117) Make QueryPlan serializable
Date Fri, 12 Feb 2010 21:08:28 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1117?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12833168#action_12833168

Edward Capriolo commented on HIVE-1117:
---------------------------------------

Personally, I think the Java XML Serialization is very cool. It is very good for dumping complex
object graphs, and you usually need to write 0 lines of de-serialization re-serialization
code. Not the tightest XML but its a very generic format. I does not seem like this portion
of the code will need to be high performance or cross platform, that would be the argument
for avro correct? 

As for JSON, well I guess I am an old timer I still like XML, anyone going to make the case
for using s-expressions :)
