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.

Temporal table support for column-organized tables

Excessive DBHEAP by BLU compression dictionaries

In current design, when SQL statement accesses a table, the compression and expansion dictionaries of that table will be read into DBHEAP and kept there until database deactivation. For column-based table, the memory consumption may up to 100MB. i...

BLU CDE Online REORG

BLU should tolerate Tools and Applications which are currently not BLU-aware

We currently employ with the introduction of db2 v10.5 BLU for our DWH. Our plan is to store almost all data in columns store. Just in exceptional cases tables should be stored row oriented. That's why we have set the registry variable DB2_WORKLOA...

Support XA transactions on column-organized tables

We have a main DW database on DB2 for z/OS and a Datamart on DB2 for LUW. Some tables on both z/OS and LUW are populated using Cobol programs which are submitted from the mainframe. We want to convert the Datamart on DB2 LUW to BLU, but the Cobol ...
