WL#5397: extend EXCHANGE PARTITION to make use of index when possible
Affects: Server-9.x — Status: Un-Assigned — Priority: Medium
Extend WL#4445 EXCHANGE PARTITION WITH TABLE to make use of INDEX if possible when verifying if the data in the table to be exchanged with a partition matches the partitions definition. i.e if the table have an index on column a, and the partitioned table is ranged partitioned on column a, it would only need to do two index lookups, one if there are any rows before the start of the partition range, and one if there are any rows after the end of the partition range. This will be much faster than scanning all rows in the table.
