Subject [jira] Commented: (HIVE-337) LazySimpleSerDe should support array and map types
Date Wed, 11 Mar 2009 22:04:50 GMT


Raghotham Murthy commented on HIVE-337:

I am not suggesting changing the serialization format for everything. just for maps and arrays.
If I have to write a new SerDe I'd have to copy over code from LazySimpleSerDe for everything
other than for maps and arrays. Can you make LazySimpleSerDe parameterizable so that it can
deserialize the old format (just single delimiters) as well as the new format (with begin-end
delimiters say) and always serialize into the new format? This will give us a migration path
to a format which is compatible with nested arrays and maps. Thoughts?
