Convert Avro to JSON

Twister pairs nicely with Jackson’s ObjectMapper since they both use POJOs.

Encode Avro Records to a JSON String

GenericRecord avroRecord = ...;
Map<String, Object> personMap = new AvroWrapper().wrap(avroRecord);
String jsonString = new ObjectMapper().writeValueAsString(personMap);

Convert Avro Record Bytes to a JSON String

Schema avroSchema = ...;
ByteBuffer avroBytes = ...;
Map<String, Object> personMap = new AvroReader().read(avroBytes, avroSchema);
String jsonString = new ObjectMapper().writeValueAsString(personMap);
