Subject [GitHub] spark pull request: [SPARK-12161][SQL] Ignore order of predicates ...
Date Wed, 09 Dec 2015 06:11:27 GMT
Github user windscope commented on the pull request:

    https://github.com/apache/spark/pull/10163#issuecomment-163121275
  
    To improve semanticEquals, we tried to implement a template function `Expression.splitWithCommutativeOperator[T:
Manifest](): Seq[Expression]` so that we don't need to implement a split function for each
commutative operator. However, we cannot perform pattern matching on T.
    Should we simply call `PredicateHelper.splitConjunctivePredicates` in `Expression.semanticEquals`
and implement a few similar split function for other commutative operators?
