推荐答案

按照官方文档 MongoDB 支持 BSON 文档的 100 级嵌套.除此之外，单个文档的大小限制为 16 兆字节.

In accordance with the official documentation MongoDB supports 100 levels of nesting for BSON documents. Beside this there's a size limitation for a single document which is 16 megabytes.

如果您有兴趣存储更大的文档，您应该阅读 GridFS.

If you are interested in storing larger documents you should read about GridFS.
