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.

Datastage 11.7.1 Snowflake Connector Upgrades Required

We have being trialling the Snowflake Connector and there's some functionality that has not yet been implemented into Snowflake Connector which greatly impacts it's performance.

1. The use TWT's - The lack of this functionality limits performance of Update/Delete modes within the connector (Snowflake quite literally processes them sequentially!)
2. There's no KEY_COLUMNS attribute within the Snowflake connector. This means we will have to rewrite jobs to no longer use generic jobs. This functionality that was previously possible with the Netezza Connector by passing in a #pKEY_COLUMNS# parameter.

    Lack of temporary tables is a serious impediment in adopting DataStage Snowflake connecor as a mainstream solution. We are considering Python or Alooma instead of DataStage.
