Build Compression Dictionary on Insert, if triggered by update or delete

There is already code that a compression dictionary is built, if rows are inserted into an empty partition. A compression dictionary is however not created if these inserts are triggered by update-statements, e.g. if you update on of the partitioning columns so that the row is moved to another partition, which is probably empty. The same is true, if you updates rows, where the pre-image is stored in a history table. Or the same may be true, if you delete rows, which are then moved to an archive table

    Thank you for submitting this enhancement request. While we view all the enhancement requests we receive as valuable and we would like to implement all of them, in an effort to have maximum transparency we are closing the ones that don’t currently appear on our two year product roadmap. This is not to say that these enhancements may not still be implemented at some point in the future as we do evaluate our requirements on the basis of customer demand and technical impact, to deliver maximum value to our customers.


    We appreciate your input to the Db2 for z/OS development team.  And we hope that you will continue to enhancement suggestions for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS. 


    Sincerely,

    The Db2 for z/OS Team
