Thread: Transformation getting slow

  1. #1

    Default Transformation getting slow


    I'm using a transformation with merge join and when it runs it takes only 3 minutes.But when I'm using the same transformation with dimension lookup/update it is taking more than half an hour.

    Will you please give me a solution for this?

    Thanking you.

    You are comparing apples and oranges there.
    Work with a DBA to make sure that your table has appropriate indices for the queries that the dimension lookup/update step is performing. Also look at your data to determine how many updates the step will be performing and make sure that the DB is tuned appropriately for that.
