mongosh Method方法

This page documents a mongosh method. This is not the documentation for database commands or language-specific drivers, such as Node.js.本页记录了一种mongosh方法。这不是数据库命令或特定语言驱动程序（如Node.js）的文档。

For the database command, see the storageSize field returned by the collStats command.对于数据库命令，请参阅collStats命令返回的storageSize字段。

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.有关MongoDB API驱动程序，请参阅特定语言的MongoDB驱动程序文档。

Returns:返回The total amount of storage in bytes allocated to this collection for document storage.分配给此集合用于文档存储的总存储量（以字节为单位）。

If collection data is compressed (which is the default for WiredTiger), the storage size reflects the compressed size and may be smaller than the value returned by db.collection.dataSize().如果集合数据被压缩（这是WiredTiger的默认值），则存储大小反映了压缩后的大小，并且可能小于db.collection.dataSize()返回的值。

To run on a replica set member, collStats operations require the member to be in PRIMARY or SECONDARY state. 要在副本集成员上运行，collStats操作要求该成员处于PRIMARY或SECONDARY状态。If the member is in another state, such as STARTUP2, the operation errors.如果成员处于另一种状态，如STARTUP2，则操作错误。
