---------------------------------------
Summary: HiveServer2: Use vectorized data whenever available for
writing final results
Key: HIVE-14551
URL: https://issues.apache.org/jira/browse/HIVE-14551
Project: Hive
Issue Type: Sub-task
Components: HiveServer2
Affects Versions: 2.1.0
Reporter: Vaibhav Gumashta
In ThriftJDBCBinarySerde, which we are using in FileSinkOperator to write final
results, we buffer rows and store them into typed columns before writing a
batch of rows to the result file. However, when vectorized rows batches are
available from higher level operators, we should try to use them and avoid the
extra penalty of converting from vector --> non-vector single row --> buffered
thrift columns (equivalent to vector).
