Jason Dere reassigned HIVE-17611:
---------------------------------
> Add new LazyBinary SerDe for faster writes
> ------------------------------------------
>
> Key: HIVE-17611
> URL: https://issues.apache.org/jira/browse/HIVE-17611
> Project: Hive
> Issue Type: Improvement
> Components: Serializers/Deserializers
> Reporter: Jason Dere
> Assignee: Jason Dere
>
> LazyBinarySerDe.serialize() ends up making
> getCategory()/getPrimitiveCategory() calls for every column of every row.
> Tried some simple tests to eliminate these calls for the non-vectorized
> version, this looks like it speeds up the writes by ~3x.
> Adding a LazyBinarySerDe2 class with this new implementation.
