    2 As I think Daniel noted in another message, you can pre-supply the extent
    3 (which is what I assume is taking a long time).  The better solution would
    4 be for me to override the OGR OCI driver's GetExtent() logic to use the
    5 USER_SDO_GEOM_METADATA as you suggest.  I kind of thought I had done that,
    6 but looking through the code I see the generic logic is used which involves
    7 reading the complete table.

    12 While a great deal of work went into optimization of the OCI driver for
    13 loading Oracle with data, the read side was not nearly as well optimized
    14 since that was not the focus of the funding project.
