IBM Data and AI Ideas Portal for Customers


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

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.

Receive notification on the decision

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.

Support mixed row/column environments without requiring CUR_COMMIT=ON

We have recently run into a problem when we enable Cur_commit because of the locking behavior expected by some applications (they expect blocking). Therefore, we have to disable CC, but then that app cannot use blu. We want to give our plant the...

pureScale load completion stage is very slow with range partitioned table

pureScale load of partition table is very slow at load completion stage, because db2 will purge local bufferpool for every partition of the table being loaded. ESE improved performance by purging once for all partitions. we wish this improvement i...
