Azure Cosmos DB 的每个帐户都有一个 master partition,它包含帐户的所有元数据。 它还具有少量的吞吐量来支持控制平面操作。 创建、读取、更新或删除此元数据的控制平面请求会消耗此吞吐量。 当控制平面操作消耗的吞吐量超过此量时,操作将受到速率限制,与 Azure Cosmos DB 中的数据平面操作相同。 但是,与数据操作...
For example, a point read (fetching a single item by its ID and partition key value) for a 1-KB item is one Request Unit (or one RU), no matter which API you use to interact with your Azure Cosmos DB container. You can model your throughput costs using the Azure Cosmos DB Capacity...
While the rule of thumb in Azure Cosmos DB is to denormalize everything and embed all data into a single item, this can lead to some situations that should be avoided. Take this JSON snippet. JSON {"id":"1","name":"What's new in the coolest Cloud","summary":"A blog post by so...
For example, a point read (fetching a single item by its ID and partition key value) for a 1-KB item is one Request Unit (or one RU), no matter which API you use to interact with your Azure Cosmos DB container. You can model your throughput costs using the Azure Cosmos DB Capacity...
As per theAzure Cosmos DB request size limit, the size of the TransactionalBatch payload cannot exceed 2MB, and the maximum execution time is 5 seconds. There is a current limit of 100 operations per TransactionalBatch to make sure the performance is as expected and within SLAs. ...
We're always busy adding new features, fixes, patches, and improvements to our Java-based client libraries for Azure Cosmos DB for NoSQL. In this regular blog series, we share highlights of recent updates in the last period.

因此，如果我们检查在循环的每个迭代中返回的项的计数，并且如果我们实现了小于或等于MaxItemCount值，...
However, you can think about the Cosmos DB constraints that can affect the RU/s used by your database. First, you need to consider the size of your items. The larger the item, the more RU/s it uses for a read or a write. Similarly, indexing consumes RU/s, and if you use the ...
Cosmos DB has a Time to Live (TTL) feature that let us specify how long we want to retain an item for. The items are deleted automatically by Cosmos DB using left-over Request Units. If your data grows into sheer size and is meant to be stored indefinitely, consider moving less ...
