Delete rows by id and range condition?

阅读更多关于 Delete rows by id and range condition?

问题 I've been searching and searching for a way to delete items with the same ID by a range condition. None of the overloads for Table.DeleteItem seem to take a range condition, only a range. Is there some other approach to deleting all entries older than an hour? I'd prefer to not not have to retrieve all the matching hashkey rows and manually delete each row by the specific range key. I'm primarily using the .NET SDK but any hints appreciated. I see some batch write examples, but nothing that
