For example, I now implement the method is to use statements to query:
result = db.collection.find_one(xxxx) if result: 更新数据 else: 插入数据
However, this method is too inefficient. I wonder if there is a better method.
MongoDB introduced a system called
upsertIf no document meets the update criteria, a new document will be created based on the criteria and the updated document. If a matching document is found, it will be updated normally.
For details, seeMongoDB’s documentation.
