Kazuaki Ishizaki updated SPARK-23879:
-------------------------------------
Component/s: Spark Core
> 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
>
> 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, ...)}}
