Hi, Why does Spark SQL need Nondeterministic trait [1] and property? That must be confusing for others not only me, right?
[1] https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/Expression.scala#L299 [2] https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/Expression.scala?utf8=%E2%9C%93#L83 Given the exact same names I suspect Nondeterministic trait does more than the name says (and property could express alone). Any plans to "fix" this (e.g. renaming the trait)?
