    Default Merge Join Behaviour

    Merge Join successfully joins the data from 2 steps and allows you to preview the data as well. BUT it does not pass data to the next step. Is this a known bug in 2.5.0? Will this be addressed in the upcoming 2.5.1 release.

    In the interim I am using the Stream Lookup to achieve partially what Merge Join would do.

    I know in 2.5 preview sometimes acts flaky but the join itself should work... can you try the transformation using merge join under the samples directory.

    Join works perfectly but it does not pass the data to the next step. I dont have any issue with the Join rather the data not getting passed to the next step, even though the preview works just fine.

    Very strange... can you try the v3?

    Cool Merge Join broken

    I just ran into this exact same bug.

    Looks like it will be resolved in 3.0:

    Fortunately, I was able to work around and use a combination of a sorted result from SQL in my table input step and a "Group By" step instead of the Merge Join step.
    Sincerly,
