Replace

Replace one document in the database.

Documentation

Replace a single document from the database matching Filter. If there are multiple matches, only the first match will be replaced.

What to replace with is specified using Replacement, which should be a complete replacement document. When upsert is active and no document matches Filter, a new document of the Replacement will be created.

Filter and Replacement can be specified either as part of the configuration or using opt-in json-ports.

See https://docs.mongodb.com/manual/reference/method/db.collection.replaceOne/ for more details.

For info on how to input data to MongoDB, see MongoDB data format.

This node can output a write operation, see Output write operation.
