-------------------------------------
Summary: Improve performance of LazyBinaryColumnarSerDe for Text
strings
Key: HIVE-12753
URL: https://issues.apache.org/jira/browse/HIVE-12753
Project: Hive
Issue Type: Bug
Components: Serializers/Deserializers
Affects Versions: 1.2.1
Reporter: David Phillips
{{LazyBinaryColumnarSerDe}} needs to special case writing empty strings, but it
does so by calling {{getPrimitiveJavaObject()}} rather than
{{getPrimitiveWritableObject()}} on {{StringObjectInspector}}. If the object is
{{Text}}, then this requires a conversion to a Java {{String}} just to get the
length.
Unfortunately, the best method to call depends on the object type (or the
object inspector type). One solution is to call
{{getPrimitiveWritableObject()}} if the object is an instance of {{Text}} or
{{BytesWritable}}.
