Hi, Mark, Sorry for the slow response.
I have not seen an sample data from you yet. Have you resolved the problem with appending data partitions? There are a couple of examples of using ibis -append option in tests/Makefile.am for targets do-small-append and do-large-append. Please take a look and see if something similar to that works for you.
