Я пытаюсь использовать symmetricds
для настройки mysql
до postgres
Синхронизация с преобразованиями. У меня очень низкая производительность при начальной загрузке с 100% загрузкой процессора на postgres
. Когда я смотрю на журнал postgres
, я обнаружил, что он использовал INSERT
. Это нормально для нормальной работы, но не для инициализации, потому что у меня есть миллионы записей. Я основал PostgresBulkDatabaseWriter
в исходном коде, который использует COPY
вместо INSERT
, и это похоже на хорошее решение (COPY
sql-запрос работает очень хорошо для меня), но я не нашел, как я могу его использовать.Массовая начальная загрузка для postgresql в SymmetricDS
Так мои вопросы:
Как лучше сделать начальную загрузку с symmetricds
для миллионов записей?
Как включить PostgresBulkDatabaseWriter
для начальной (обратной начальной) нагрузки?
Благодаря
