Hi, I am trying to pick up the outer join operator. However, as Fabian mentioned to me, that this task would require to touch many different components of the system, it would be a challenge job for me. Therefore I would need some help:-)
I might need to walk through some features like Compiler/Optimizer and Runtime(as Fabian mentioned to me), so where should I start to get familiar? One more thing, is the outer join operator implementation similar to the pure join operator? Best, Wilson Cao
