根因分析

插入或更新的文档超过了 MongoDB 的 16MB BSON 文档大小限制。

English

The document being inserted or updated exceeds MongoDB's 16MB BSON document size limit.

解决方案

  1. Use GridFS to store large documents. Split the document into chunks and store them in fs.files and fs.chunks collections. Example: `mongofiles put large_document.json`
  2. Restructure the document to remove large arrays or subdocuments, storing them in separate collections with references.

无效尝试

常见但无效的做法:

  1. 100% 失败

    MongoDB's 16MB limit is hardcoded and cannot be changed; no such startup parameter exists.

  2. 90% 失败

    Compression must be done at the storage engine level (WiredTiger), not by the application; the BSON size check occurs before storage.
