Vaibhav Gumashta resolved HIVE-13595. ------------------------------------- Resolution: Later We've investigated the idea of implementing VectorizedSerde interface for writing final results, but as of now there are some issues: 1. Not all datatypes are vectorized. 2. For the ones that are, we'll also need to avoid the vector --> row --> columnar translation we're doing. 3. For final write, we'll need to use VectorFileSinkOperator instead of FileSinkOperator. We'll take up these as separate jiras in HIVE-14549. Thanks [~ziyangz] for the investigation. > HiveServer2: Evaluate if ThriftJDBCBinarySerde should implement > VectorizedSerde > ------------------------------------------------------------------------------- > > Key: HIVE-13595 > URL: https://issues.apache.org/jira/browse/HIVE-13595 > Project: Hive > Issue Type: Sub-task > Components: HiveServer2 > Affects Versions: 2.1.0 > Reporter: Vaibhav Gumashta > Assignee: Ziyang Zhao > > As part of HIVE-12049, ThriftJDBCBinarySerde was introduced which buffers > rows and writes thrift converted columnar row batches as part of the final > task output. Hive has VectorizedSerde which is used during vectorized > operations. We should explore if ThriftJDBCBinarySerde should implement that. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
