* `db.collection.` `totalSize` ()

|     |                                                                                                                              |

| 返回： | 集合中数据的总大小(以字节为单位)加上集合中每个索引的大小。 如果压缩了集合数据(即WiredTiger 的默认值)，则返回的大小反映了集合数据的压缩大小。 如果索引使用前缀压缩(即WiredTiger 的默认值)，则返回的大小反映索引的压缩大小。 |

返回的 value 是db.collection.storageSize()和db.collection.totalIndexSize()的总和(以字节为单位)。
