MongoDB Save

The MongoDB Save node saves documents that were previously read from a MongoDB database and then modified. For each document in the input column a document with corresponding _id field is looked up and its fields replaced with the fields from the document in the table. If no such document exists in the database, the document from the table is inserted. Therefore the behavior is equal to an update with the upsert option turned on.
