Help IBM prioritize your ideas and requests
The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.
Performance degradation and difference in behavior of access plan on stored procedure query after enabling RCAC - column masking for a column which is part of select condition.
The query access plan without RCAC is scanning only the table (Table A) and the query plan with RCAC its going for entire view scan/filter instead of single table (Table A) it scan/filter for all the tables in view.
By this additional scan/filter performance of the select query is getting impacted.As this is design and expected behavior of RCAC,if the security feature creates the performance degradation for union all scenarios. How the vendors can compromise the performance impact by using the security features.
Please consider this request and have enhancement for this performance impact.
