Jark Wu updated FLINK-32610:
----------------------------
Release Note: The JSON format introduced JsonParser as a new default way to
deserialize JSON data. JsonParser is a Jackson JSON streaming API to read JSON
data which is much faster and consumes less memory compared to the previous
JsonNode approach. This should be a compatible change, if you encounter any
issues after upgrading, you can fallback to the previous JsonNode approach by
setting `json.decode.json-parser.enabled` to `false`. (was: The JSON format
