  • Fixes [Bug] Failed to deserialize consumer record #5945
  • KafkaDebeziumJsonDeserializationSchema always parses Kafka keys as JSON, causing deserialization for fail for non JSON
  • CDC pipelines only use the JSON value payload, handle this gracefully by ignoring the non json fields.
  • Prevents crashes for topics with raw keys.
