Я использую AWS Database Migration Service (DMS) для создания задач репликации. Я заметил, что в JS TaskSettings есть атрибут с именем CharacterSetSettings
. Однако, похоже, нет документации для этого атрибута.
Я пытался найти документацию, и Google для этого атрибута ничего не появляется.

На * 1009 должна быть документация. Предполагается, что эта документация будет указана в Указание параметров задачи для задач службы миграции баз данных AWS - Служба миграции базы данных AWS .
