When using Automatic Schema Generation, is it possible to define the defaults. For example, we noticed that tables are created with:

WITH(
  'comment' = 'Created on insertion',
  merge_mode = 'last_non_null'
)

but in our use case:

WITH(
  append_mode = 'true',
  sst_format = 'flat'
);

Is more performant for us, and is almost always the right thing.

You can specify the HTTP header

x-greptime-hints: append_mode=true, sst_format=flat

to set the table options.
