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.

John
