Paulo Motta commented on CASSANDRA-10854:
-----------------------------------------
With the current approach if you try to insert an empty {{int}} value, the
message will vary:
* {{Failed to import 4 rows: ValueError - invalid literal for int() with base
10: '' - given up after 1 attempts}} will be print if {{WITH NULL}} is set.
* {{Failed to import 4 rows: ValueError - Cannot insert null value for primary
key column 'bla'. If you want to insert empty strings, consider using the WITH
NULL=<marker> option for COPY. - given up after 1 attempts}} will be print if
{{WITH NULL}} is not set.
So it would be nice to unify those. And I think we can also get rid of the
{{If you want to insert empty strings, consider using the WITH NULL=<marker>
option for COPY}} message, since even if it's a text, we cannot have nulls in
the primary keys so this might confuse users.
I'd vote for just having the message {{Failed to import 1 rows: ValueError -
Cannot insert null value for primary key column 'bla2'}}, regardless of type
and if nullval is set.
