Is there any performance or size difference with column order in SQLITE ? similar to this https://www.cybertec-postgresql.com/en/column-order-in-postgresql-does-matter/

It might be interesting to have an option to create with an optimized column order. I'm assuming this would look something like INTEGER columns, REAL columns, BLOB columns, TEXT columns, NULL columns. NULL columns at the end because they are more likely to be TEXT and it is impossible to know if they will become INTEGER

(Of course, any schema evolution would reduce optimization but maybe column order could also be re-evaluated when schema changes)

edit:

this is easy to accomplish with the existing transform method:

int_columns = [k for k, v in table_columns.items() if v == int] db[table].transform(column_order=[*int_columns])
