             Summary: Writing to an object store (without intermediate file)
                 Key: AVRO-3472
                 URL: https://issues.apache.org/jira/browse/AVRO-3472
             Project: Apache Avro
          Issue Type: New Feature
          Components: java
         Environment: OpenJDK version 11 on Ubuntu
            Reporter: Kevin A Shaw


We need to write a large number files for a production system to an Object 
Store (AWS S3 in this case) which cannot be represented by a java.io.File 
object.  We are currently using a DataFileWriter() to create a file in a /tmp 
directory, putting it to S3 and then deleting the file.  This is becoming 
cumbersome and just seems inefficient.  Is there a way to instead create the 
file using an in-memory object, instead of writing to disk?
