Hi
I've been testing some different serialization techniques, to use in
a research project.
I know motivation behind hadoop serialization mechanism (e.g.
Writable) and the enhancement of this feature through record I/O is
not only performance, but also control of the input/output.
Still I've been running some simple tests and I've foud that plain
RMi beats Hadoop RecordIO almost every time (14-16% faster).
In my test I have a simple java class that has 14 int fields and 1
long field and I'm serializing aroung 35000 instances.
Am I doing anything wrong? are there ways to improve performance in
RecordIO? Have I got the use case wrong?
Regards
David Alves
