 Creates an Iceberg table whose structure matches the Redpanda schema for the topic, with columns corresponding to each field. You must register a schema in the xref:manage:schema-reg/schema-reg-overview.adoc[Schema Registry] and producers must write to the topic using the Schema Registry wire format.
 
 In the xref:manage:schema-reg/schema-reg-overview.adoc#wire-format[Schema Registry wire format], a "magic byte" and schema ID are embedded in the message payload header. Producers to the topic must use the wire format in the serialization process so Redpanda can determine the schema used for each record, use the schema to define the Iceberg table, and store the topic values in the corresponding table columns.
 
+[[value_schema_latest]]

 Creates an Iceberg table whose structure matches the latest schema registered for the subject in the Schema Registry. You must register a schema in the Schema Registry.
