------------------------------------------
Summary: Optimize vector row serde to avoid type check at run time
Key: HIVE-24503
URL: https://issues.apache.org/jira/browse/HIVE-24503
Project: Hive
Issue Type: Bug
Components: Hive
Reporter: mahesh kumar behera
Assignee: mahesh kumar behera
Serialization/Deserialization of vectorized batch done at VectorSerializeRow
and VectorDeserializeRow does a type checking for each column of each row. This
becomes very costly when there are billions of rows to read/write. This can be
optimized if the type check is done during init time and specific reader/writer
classes are created.
