Description

Generating insert events should not be conditional to events processor being active or not.

Please note that this will also need to fix a bug in the createInsertEvents() code as an INSERT with an empty result set raises an IllegalStateException:

create table ctas_empty as select * from functional.alltypes limit 0;
