--------------------------------------
Summary: Enable use of MongoDB Operators as a NiFI Property
Key: NIFI-5506
URL: https://issues.apache.org/jira/browse/NIFI-5506
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 1.7.1, 1.7.0, 1.6.0
Reporter: Ryan Hendrickson
Currently, the PutMongo processor allows the use of MongoDB Operators, when the
query is passed in as a FlowFile to the processor. Additionally, you can also
put an update query into the Property Field, however, it doesn't allow MongoDB
Operators.
This ticket is to express that a more flexible solution is needed, such that,
you can update singular fields in a Mongo Document using the PutMongo processor
in-line with a normal flow, vs having to create a file for it, making use of
Mongo Operators and NiFi Expression Language.
An example solution, could look like: A drop-down combo box in the UI that asks
which Mongo Operator you'd like to use: $set, $unset, etc., then a text field
supporting Expression Language for the JSON values.
Example of: \{"id":"${id}", $set: \{"field1":"anything"}, would be expressed in
the UI as:
Mode: update
Update Query: \{"id":"${id}"}
Mongo Operator: $set (from DropDown)
Operator Update Values: \{"field1":"anything"}
Update Mode: With operators enabled
