Jason Dere updated HIVE-17611: ------------------------------ Status: Patch Available (was: Open) > 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 > Attachments: HIVE-17611.1.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
