db.collection.totalIndexSize()¶

db.collection.totalIndexSize()¶

mongo Shell Method

This page documents the mongo shell method, and does not refer to the MongoDB Node.js driver (or any other driver) method. 本页记录了mongo shell方法，未提及MongoDB Node.js驱动程序（或任何其他驱动程序）方法。For corresponding MongoDB driver API, refer to your specific MongoDB driver documentation instead.有关相应的MongoDB驱动程序API，请参阅特定的MongoDB驱动程序文档。

Returns:返回：	The total size of all indexes for the collection.集合的所有索引的总大小。 If an index uses prefix compression (which is the default for WiredTiger), the returned size reflects the compressed size.如果索引使用前缀压缩（这是WiredTiger的默认值），则返回的大小将反映压缩后的大小。

This method provides a wrapper around the totalIndexSize output of the collStats (i.e. db.collection.stats()) operation.此方法为collStats（即db.collection.stats()）操作的totalIndexSize输出提供包装。

Starting in MongoDB 4.4, to run on a replica set member, collStats operations require the member to be in PRIMARY or SECONDARY state. 从MongoDB 4.4开始，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，例如STARTUP2，则操作会出错。

In previous versions, the operations can also be run when the member is in STARTUP2. 在以前的版本中，当成员在STARTUP2中时，也可以运行这些操作。However, the operations wait until the member transitions to RECOVERING.但是，这些操作将等待成员转换到RECOVERING。
