While we're on it, we can simply remove this one as well. What do you think?

yes, makes sense. So the two remaining features to list as not implemented are:

  • Don't support creating iceberg table with hidden partitioning. Discussion in flink mail list.
  • Don't support creating iceberg table with computed column.

is that right?

Yes @rmoff, those are the 2 last missing features mentioned here.
Could you please update the doc accordingly?

Thanks,
Peter
