mongodb - MongoDB check the time of document log

Question

I have a collection which stores a array of strings as a part of document and _id , is there a possibility that I can check the timestamp of any of the document which is logged. the document structure is:

{ "_id" : NumberLong(1370891970), "k" : [ "argos","test"]}

Appreciate your help in advance.

Answer 1

如果这是您的文档结构，则无法检查它。您的任何字段都不包含此信息，并且您还覆盖了您的_id字段。
