Hi Burkhard, I tried using the autoscaler, however it did not give a suggestion to resize pg_num. Since my pg_num is not a power of 2, I wanted to fix that first, manually, to only realize that it didn’t work. Because changing pg_num manually did not work, I am not convinced that the autoscaler will work, either, when the time comes. The autoscaler pg_num changes would follow the same execution path as manual changes, won’t they? Thanks!
