There are 2 ways to support this, with tradeoff between performance and backward compatibility: 1. Send back a bitmap per column from server to broker to mark the null values (extra overhead but fully backward compatible) 2. Reserve a special value per data type to represent the null value (no extra overhead, but all reserved value will be treated as null) We can start with option 1, and if necessary, we may build option 2 and use a flag to switch between them -- This is an automated message from the Apache Git Service.
