> BlockManager should expose getRemoteManagedBuffer to avoid creating
> bytebuffers
> -------------------------------------------------------------------------------
>
> Key: SPARK-25905
> URL: https://issues.apache.org/jira/browse/SPARK-25905
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.4.0
> Reporter: Imran Rashid
> Priority: Major
> Labels: memory-analysis
>
> The block manager currently only lets you get a handle on remote data as a
> {{ChunkedByteBuffer}}. But with remote reads of cached data, you really only
> need an input stream view of the data, which is already available with the
> {{ManagedBuffer}} which is fetched. By forcing conversion to a
> {{ChunkedByteBuffer}}, we end up using more memory than necessary.
