Mongodb 批量写入错误 [英] Mongodb bulk write error

问题描述

我正在执行批量写入

bulk = new_packets.initialize_ordered_bulk_op()

bulk.insert(packet)

output = bulk.execute()

并得到一个错误，我解释为该数据包不是字典.但是，我确实知道这是一个字典.可能是什么问题?

and getting an error that I interpret to mean that packet is not a dict. However, I do know that it is a dict. What could be the problem?

这里是错误:

    BulkWriteError                            Traceback (most recent call last)

          3 bulk.insert(packet)
    ----> 4 output = bulk.execute()

    --> 298             raise BulkWriteError(full_result)
299         return full_result
300 

    BulkWriteError: batch op errors occurred

推荐答案

好吧，问题是我显式分配了 _id，结果发现字符串大于 12 字节限制，我不好.

Ok, the problem was that i was assigning _id explicitly and it turns out that the string was larger than 12-byte limit, my bad.
