Suraj Menon created HAMA-706:
--------------------------------
Summary: Keep new object creation to the minimum by reusing the
Writable object
Key: HAMA-706
URL: https://issues.apache.org/jira/browse/HAMA-706
Project: Hama
Issue Type: Improvement
Components: bsp core
Reporter: Suraj Menon
Fix For: 0.6.1
In all the examples and some core modules, we create new Writable objects,
which is not recommended when we are handling huge data size with billions of
records, causing a huge GC overhead. It is better that we reuse Writable object
and populate the values instead. In places where the aforesaid principle is not
followed, the suggested changes should be made. This would be useful once the
spilling buffer is fully functional.
