Subject problem with reading source code-pull out nondeterministic expresssions
Date Wed, 30 Dec 2015 06:57:28 GMT
Hi fellas,
I am new to spark and I have a newbie question. I am currently reading the source code in
spark sql catalyst analyzer. I not quite understand the partial function in PullOutNondeterministric.
What does it mean by "pull out”? Why do we have to do the "pulling out”?
I would really appreciate it if somebody explain it to me.
