> Key: FLINK-7310
> URL: https://issues.apache.org/jira/browse/FLINK-7310
> Project: Flink
> Issue Type: Sub-task
> Components: Core
> Affects Versions: 1.4.0
> Reporter: Nico Kruber
> Assignee: Nico Kruber
> Fix For: 1.4.0
>
>
> For future changes to the network buffers (sending our own off-heap buffers
> through to netty), we cannot use {{HeapMemorySegment}} anymore and need to
> rely on {{HybridMemorySegment}} instead.
> We should thus drop any code that loads the {{HeapMemorySegment}} (it is
> still available if needed) in favour of the {{HybridMemorySegment}} which is
> able to work on both heap and off-heap memory.
> FYI: For the performance penalty of this change compared to using
> {{HeapMemorySegment}} alone, see this interesting blob article (from 2015):
> https://flink.apache.org/news/2015/09/16/off-heap-memory.html
