Translates tables and enums defined with Database Markup Language (DBML) to Apache Avro schemas in JSON format.
Using Java 17.
Example usage:
import com.wn.dbml.avro.Config;
import com.wn.dbml.avro.DbmlAvroTranslator;
import com.wn.dbml.avro.DbmlAvroTranslator.Result;
class Example {
public static void main(String[] args) {
var dbml = """
Table User {
id integer [not null]
name varchar
}""";
var config = Config.builder().setNamespace("com.example").build();
// translate the DBML to Avro schemas
var translated = new DbmlAvroTranslator(config).translate(dbml);
// process the Avro schema JSONs
translated.stream()
.map(Result::schema)
.forEach(System.out::println);
}
}The resulting schema will look like this:
{
"type": "record",
"name": "User",
"namespace": "com.example",
"fields": [
{"name": "id", "type": "int"},
{"name": "name", "type": ["string", "null"]}
]
