> Problem found here: [https://nightlies.apache.org/flink/flink-docs-master/docs/connectors/table/formats/debezium/#how-to-use-debezium-format.]
> Here is the example provided:
> {code:java}
> CREATE TABLE topic_products (
>   -- schema is totally the same to the MySQL "products" table
>   id BIGINT,
>   name STRING,
>   description STRING,
>   weight DECIMAL(10, 2)
> ) WITH (
>  'connector' = 'kafka',
>  'topic' = 'products_binlog',
>  'properties.bootstrap.servers' = 'localhost:9092',
>  'properties.group.id' = 'testGroup',
>  -- using 'debezium-json' as the format to interpret Debezium JSON messages
>  -- please use 'debezium-avro-confluent' if Debezium encodes messages in Avro format
>  'format' = 'debezium-json'
> ) {code}
> Actually, `debezium-json` would require `'debezium-json.schema-include' = 'true'` to work (as, by default, Debezium includes the schema. See [https://www.markhneedham.com/blog/2023/01/24/flink-sql-could-not-execute-sql-statement-corrupt-debezium-message/).]
> On the other hand `debezium-avro` would require the URL of the Confluent schema registry: `'debezium-avro-confluent.url' = '[http://...:8081'.]
> I propose to split the single example in 2 with the correct default options.
