                 Key: AVRO-24
                 URL: https://issues.apache.org/jira/browse/AVRO-24
             Project: Avro
          Issue Type: Task
          Components: java
            Reporter: Doug Cutting

             Fix For: 1.0


It would be good to validate that the RPC wire format is capable of 
transmitting bulk data efficiently.  In particular, to be used for HDFS file 
access, it must be able to, when including file data in an RPC response, or 
writing file data in an RPC request:
 - saturate a disk's throughput or a network interface; and
 - not consume much CPU.
In other words, Avro's RPC should not be a bottleneck in the transfer of file 
data from a remote disk to an application or vice versa, and moreover it should 
leave the vast majority of the CPU for the application.
