Класс KustoIngestionProperties

Класс KustoIngestionProperties содержит базовые свойства приема для точного управления процессом приема.

Свойство Значение
имя_базы_данных Имя базы данных для приема
TableName Имя таблицы для приема
DropByTags Теги, которые будут иметь каждый экстент. DropByTags являются постоянными и могут использоваться следующим образом: .show table T extents where tags has 'some tag' или .drop extents <| .show table T extents where tags has 'some tag'
IngestByTags Теги, записываемые для каждого экстента. Позже можно использовать со свойством IngestIfNotExists , чтобы не принимать одни и те же данные дважды. Дополнительные сведения см. в разделе о тегах ingest-by:.
IngestionMapping Содержит ссылку на сопоставление выхода или список сопоставлений столбцов.
Дополнительные теги Дополнительные теги по мере необходимости
IngestIfNotExists Список тегов, которые вы не хотите принимать снова (для каждой таблицы)
ValidationPolicy Определения проверки данных.
Формат Формат данных, которые принимаются
AdditionalProperties Другие свойства, передаваемые в качестве свойств приема команде приема. Свойства передаются, так как не все свойства приема представлены в отдельном элементе этого класса.

Класс KustoQueuedIngestionProperties

Класс KustoQueuedIngestionProperties расширяет KustoIngestionProperties несколькими ручками управления, которые можно использовать для точной настройки поведения приема.

Свойство Значение
FlushImmediately По умолчанию — false. Если задано значение true, будет обходить механизм агрегирования службы Управление данными
IngestionReportLevel Управляет уровнем отчетов о состоянии приема (по умолчанию — FailuresOnly). Для повышения производительности и использования хранилища рекомендуется не задавать для параметра IngestionReportLevel значение . FailuresAndSuccesses
IngestionReportMethod Управляет целевым объектом отчетов о состоянии приема. Доступные варианты: Очередь Azure, Таблица Azure или и то, и другое. По умолчанию — Queue.
