 ## Why?
 
-Most sink connectors in kafka-connect require a schema to insert the data. When dealing with topics that contain plain JSON records it's not possible to insert them them without an inline schema, as explained [here](https://rmoff.net/2020/01/22/kafka-connect-and-schemas/)
+Most sink connectors in kafka-connect require a schema to insert the data. When dealing with topics that contain plain JSON records it's not possible to insert them them without an inline schema, as explained [here](https://www.confluent.de/blog/kafka-connect-deep-dive-converters-serialization-explained/#string-json-data)
 
 Sometimes it is just not possible to change the JSON records to include the schema and we are okay with having the json "as-is" in the sink system. This still allows a "schema-on-read"-strategy, supported by RDBMS like MySql and Postgres with their JSON data types.
