Subject [jira] Commented: (PIG-794) Use Avro serialization in Pig
Date Thu, 02 Sep 2010 17:57:56 GMT

    [ https://issues.apache.org/jira/browse/PIG-794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12905612#action_12905612

Dmitriy V. Ryaboy commented on PIG-794:
---------------------------------------

Doug and Scott will know better of course, but afaik, Avro doesn't support Object keys.

You can cheat and turn Object keys into strings by Base64-encoding their serialized representations..
you'd have to know to reverse the process when deserializing, though.

Or we can try to get rid of InternalMap.

> We would like to use Avro serialization in Pig to pass data between MR jobs instead of
the current BinStorage. Attached is an implementation of AvroBinStorage which performs significantly
better compared to BinStorage on our benchmarks.
