[jira] [Resolved] (SPARK-23879) Introduce MemoryBlock API instead
of Platform API with Object
[ https://issues.apache.org/jira/browse/SPARK-23879?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hyukjin Kwon resolved SPARK-23879.
----------------------------------
Resolution: Incomplete
> Introduce MemoryBlock API instead of Platform API with Object
> --------------------------------------------------------------
>
> Key: SPARK-23879
> URL: https://issues.apache.org/jira/browse/SPARK-23879
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, SQL
> Affects Versions: 2.3.0
> Reporter: Kazuaki Ishizaki
> Priority: Major
> Labels: bulk-closed
>
> This JIRA is derived from SPARK-10399.
> During the discussion, the community revealed that current Spark framework directly accesses several types of memory regions (e.g. {{byte[]}}, {{long[]}}, or {{Off-heap}}) by using {{Platform API with }}{{Object}} type. It would be good to have unified memory management API for clear memory model.
> It is also good for performance. If we can pass typed object (e.g.{{byte[]}}, {{long[]}}) to {{Platform.getXX()/putXX()}}, it is faster than using {{Platform.getXX(Object)/putXX(Object, ...)}}
