-----------------------------------
Summary: ORC should provide raw data size
Key: HIVE-4340
URL: https://issues.apache.org/jira/browse/HIVE-4340
Project: Hive
Issue Type: Improvement
Components: Serializers/Deserializers
Affects Versions: 0.11.0
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
ORC's SerDe currently does nothing, and hence does not calculate a raw data
size. WriterImpl, however, has enough information to provide one.
WriterImpl should compute a raw data size for each row, aggregate them per
stripe and record it in the strip information, as RC currently does in its key
header, and allow the FileSinkOperator access to the size per row.
FileSinkOperator should be able to get the raw data size from either the SerDe
or the RecordWriter when the RecordWriter can provide it.
