   @RussellSpitzer I believe `TestIdentityPartitionData` is supposed to exercise it but what is probably happening here is that the identity partitioned data columns are read from the data file itself rather than the metadata. We may need to add a test where we intentionally modify the metadata so that identity values from metadata do not match the ones written in the data file so we know where the values are picked from. Maybe theres a less intrusive way to test this?
