Tao Li commented on HIVE-15717:
-------------------------------
The local test shows 50% improvement in terms of beeline output time. The
latency was reduced from 12 sec to 6 sec with the optimization.
> Class "org.apache.hive.beeline.Rows.Row" constructor is CPU consuming due to

> The exception handling from the 3 methods calls (rowDeleted, rowInserted and
> rowUpdated). The implementation of these methods in
> org.apache.hive.jdbc.HiveBaseResultSet class is just throwing
> SQLException("Method not supported”), i.e. no real implementations.
