我有一个cosmosDB,它在数据库级别提供了4个容器和400RU。我添加了2个容器,并且在没有警告的情况下,预配置的RU增加到600。
以下文档说明了这种情况的发生原因。高于第4个的每个容器至少需要额外的100RU。我的预算限制很严格,因此我删除了2个容器,但找不到降低最低预配置吞吐量的方法,因为预配置吞吐量的下拉列表仅允许增加。有没有办法降低吞吐量?

如document中所述,您可以使用cosmos db sdk减少吞吐量设置。例如,我测试Java SDK以减少容器吞吐量设置。请参考以下代码:
import com.microsoft.azure.documentdb.*;
import java.util.Iterator;
public class ChangeRUTest {
static private String YOUR_COSMOS_DB_ENDPOINT = "https://***.documents.azure.com:443/";
static private String YOUR_COSMOS_DB_MASTER_KEY="***";
public static void main(String[] args) throws DocumentClientException {
DocumentClient client = new DocumentClient(
YOUR_COSMOS_DB_ENDPOINT,
YOUR_COSMOS_DB_MASTER_KEY,
new ConnectionPolicy(),
ConsistencyLevel.Session);
String collectionLink = "dbs/test/colls/one";
String collectionResourceId = client.readCollection(collectionLink, null).getResource().getResourceId();
// find offer associated with this collection
Iterator<Offer> it = client.queryOffers(
String.format("SELECT * FROM r where r.offerResourceId = '%s'", collectionResourceId), null).getQueryIterator();
Offer offer = it.next();
System.out.println(offer.getContent().getInt("offerThroughput"));
// update the offer
int newThroughput = 400;
offer.getContent().put("offerThroughput", newThroughput);
client.replaceOffer(offer);
}
}
