Thread: Large database join gives "OutOfMemoryError"

    Exclamation Large database join gives "OutOfMemoryError"

    I have a transformation that works with small-ish numbers of rows, but gives a memory error with larger numbers.

    It actually sounds a lot like story 2 at bug #2759, but I don't understand the solution to that bug.

    I've attached the log for more detail.

    The story is most likely unrelated although you can try to lower the row set size in the transformation to see if that makes a difference.

    Matt: That was exactly the solution!

    Where do I find documentation on what "rowset size" means?

    I also found that when I removed some slow steps from the end of my long transformation (Table Output), the buffers don't fill and I no longer have memory issues.
