public final class OpProcFactory
- extends Object
Operator factory for partition pruning processing of operator graph We find
all the filter operators that appear just beneath the table scan operators.
We then pass the filter to the partition pruner to construct a pruner for
that table alias and store a mapping from the table scan operator to that
pruner. We call that pruner later during plan generation.
