title: Can I Write Two Schemas in One AVRO File
body: <p>I have data like this: schema1, a1, a2, ..., an, schema2, b1, b2, ...., bm. I know exactly how many data items I have for each schema. Can I write the two schema/data in one AVRO file, instead of two?</p>
  
  <p>dataFileWrite API gives only create(). There is no append() for me to writer the second schema after the last data item of the first schema.</p>
