Perform Bulk Operations

Example

The following example performs the following in order on the haikus collection:

• Matches a document in which the title is "Record of a Shriveled Datum" and replace it with a new document

• Matches a document in which the title is "Dodging Greys" and updates that value to "Dodge The Greys"

coll := client.Database("insertDB").Collection("haikus")
models := []mongo.WriteModel{
	mongo.NewReplaceOneModel().SetFilter(bson.D{{"title", "Record of a Shriveled Datum"}}).
		SetReplacement(bson.D{{"title", "Dodging Greys"}, {"text", "When there're no matches, no longer need to panic. You can use upsert"}}),
	mongo.NewUpdateOneModel().SetFilter(bson.D{{"title", "Dodging Greys"}}).
		SetUpdate(bson.D{{"$set", bson.D{{"title", "Dodge The Greys"}}}}),
}
opts := options.BulkWrite().SetOrdered(true)
results, err := coll.BulkWrite(context.TODO(), models, opts)

Expected Result

After you run the full example, you can find the following document in the haikus collection:

{
   "_id" : ObjectId("..."),
   "title" : "Dodge The Greys",
   "text" : "When there're no matches, no longer need to panic. You can use upsert."
}
