While it is possible and common to embed multiple documents using array fields, if the list of objects grows uncontrollably the document could quickly reach this size limit. Q&A for work. Refer the below screenshot: Code: In Compass, use the left navigation panel to select the database and the collection you want to import the data to. We can specify the particular date by passing the date as an ISO-8601 date string, and this string is used with the range as 0 to 9999 to the new date() function in MongoDB. The added key is Insert Date, which is a timestamp as of when the insertion operation happened. For clarity, this tutorial will refer to the four servers as follows: mongo-config, which will function as the clusters config server. The ISODate is in UTC..
