Avro is a row-based data serialization format used in big data systems (Kafka, Spark, Hadoop). It uses JSON-defined schemas to specify data structure, enabling compact binary encoding and schema evolution.
All Avro types: string, int, long, float, double, boolean, bytes, null, record, enum, array, map, and union (nullable fields). Nested records are fully supported.
Yes. Each field can have a default value that matches its type. Default values enable schema evolution — new fields can be added without breaking existing readers.
The output is valid Avro schema JSON that can be used directly with Avro serializers, Kafka schema registries, or Spark/Flume/Hadoop configurations.
No. All generation happens locally in your browser. No schema data is sent to any server.
