Subject Buffered result status
Date Sun, 27 Sep 2015 14:36:30 GMT
Dears,

I was looking in the base code of the Distributed result and I found that
the result can be buffered. i.e. the result temp file will only be written
if the number of available memory pages < the result size. The buffer
policy is LRU as
in org.apache.hyracks.control.nc.dataset.DatasetMemoryManager.evictPage()

The memory size can be configured in the NCConfig with the
option: -result-manager-memory
Is it an undocumented feature?

@Yingyi is that similar to what you referred to as (Hyracks Buffer Cache) ?

Thanks!
