I am trying to update bulk of documents in collection using mongodbwith different values for field. I have unique Id for each document. I need to update bulk of records in single update command. How do we update bulk of documents. Please suggest the approaches to solve this.

bulkWrite(). Is there actually a question other than "Please search the documentation for me"? — Neil Lunn

You can update multiple records with below command,

db.getCollection('collectionName').update({'condition if any'},{$set: { field:value}}, {multi:true})
