title: Partial deserialization with Apache Avro
body: <p>Is it possible to deserialize a subset of fields from a large object serialized using Apache Avro without deserializing all the fields? I'm using <code>GenericDatumReader</code> and the <code>GenericRecord</code> contains all the fields.</p>
  <p>I'm pretty sure you can't do it using <code>GenericDatumReader</code>, but my question is whether it is possible given the binary format of Avro.</p>
