MongoDB Reader

KNIME MongoDB Nodes (Preview) version 4.3.0.v202011191336 by KNIME AG, Zurich, Switzerland

The MongoDB Reader node reads documents from a MongoDB database and returns them as JSON cells in a table. The node uses Jongo to retrieve the documents and therefore the query, projection and sorting notation is the same as described in the Jongo documentation and very close to how querying is done in the MongoDB shell.

Options

Host: The host name or ip address
Port: The port on which the database is available (default: 27017)
Database: The database name
Collection: The collection name
Query: The query selecting the documents to retrieve
Projection: The projection of fields of the retrieved documents
Sorting: The sorting of the documents

Output Ports

: The result json returned by mongodb
