------------------------------
Summary: Support fail-on-unknown-field config in json format
Key: FLINK-35427
URL: https://issues.apache.org/jira/browse/FLINK-35427
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Reporter: huhuan
In many cases, the consumer and producer of message queues come from different
teams, or even different companies.
As message consumer, sometimes it is difficult to subscribe updates on message
format, which may result in data loss.
We want to ensure the message format strictly matches the schema, if some field
is missing or new field is added, it is better to fail the application so that
we can notice and fix it quickly.
In this case, a fail-on-unknown-field config for JSON format could be very
helpful, especially when works with fail-on-missing-field.
