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.

Allow partial indexes in all editions

IDS 14.10 contains this important new feature:

https://www.ibm.com/support/knowledgecenter/SSGU8G_14.1.0/com.ibm.sqls.doc/ids_sqs_partial_index.htm

"Partial indexes avoid indexing common values. As the query searching for a common value will not use the index, there is no point in keeping those rows in the index. This reduces the size of the index, which will speed up queries that do use the index. It will also speed up many table update operations because the index does not need to be updated in all cases."

We understand that tables comprised of multiple fragments (partitions) is part of the parallelisation features reserved for Enterprise Edition. Unfortunately, partial indexes has been implemented using the FRAGMENT BY EXPRESSION (or PARTITION) syntax, and this is rejected on lower editions (except Developer). Using the example table from the above documentation page:

CREATE INDEX idx2 ON tab1 (n2)
FRAGMENT BY EXPRESSION
(n2 IS NULL) INDEX OFF,
REMAINDER IN datadbs;

26453: Fragmentation is not supported in this edition of IDS
