MongoDB Save

KNIME MongoDB Nodes (Preview) version 4.2.0.v202006171547 by KNIME AG, Zurich, Switzerland

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.

Host

Port

Database
The database name
Collection
The collection name
Input column
The column which contains the documents to be saved
