Hyukjin Kwon updated SPARK-5915:
--------------------------------
Labels: bulk-closed (was: )
> Spillable should check every N bytes rather than every 32 elements
> ------------------------------------------------------------------
>
> Key: SPARK-5915
> URL: https://issues.apache.org/jira/browse/SPARK-5915
> Project: Spark
> Issue Type: Improvement
> Components: Shuffle, Spark Core
> Affects Versions: 1.0.0
> Reporter: Mingyu Kim
> Priority: Major
> Labels: bulk-closed
>
> Spillable currently checks for spill every 32 elements. However, this puts it
> at a risk of OOM if each element is large enough. A better alternative is to
> check every N bytes accumulated.
> N should be decided to a reasonable number via proper testing.
> This is a follow-up of SPARK-4808, and was discussed originally in
> https://github.com/apache/spark/pull/4420.
