Description

Implements dynamic partition pruning by adding a dynamic-partition-pruning filter if there is a partitioned table and a filter on the dimension table. The filter is then planned using a heuristic approach:

1. As a broadcast relation if it is a broadcast hash join. The broadcast relation will then be transformed into a reused broadcast exchange by the ReuseExchange rule; or
2. As a subquery duplicate if the estimated benefit of partition table scan being saved is greater than the estimated cost of the extra scan of the duplicated subquery; otherwise
3. As a bypassed condition (true).

 Below shows a basic example of DPP.
