…-predicate-pushdown
Previously, the expresison builder would return null for unsupported expressions, but it is unclear whether that behavior is correct. Instead, if the expression can't be converted to a filter, this will throw an exception so it can be rewritten. This also implements "in", "between", "!=", and "not" expressions.
| buildFilter(OpType.OP_GE, (Column) lhs, (Const) between.getLower()), | ||
| buildFilter(OpType.OP_LE, (Column) lhs, (Const) between.getUpper())); | ||
| case OP_IN: | ||
| FilterPredicate current = null; |
There was a problem hiding this comment.
BETWEEN and IN aren't currently supported in Pig and there's still some question on the bounds (inclusive vs. exclusive) so we might want to comment these out for now and put a TODO. (I guess this should be commented out in getSupportedExpressionTypes()
