> Key: FLINK-12696
> URL: https://issues.apache.org/jira/browse/FLINK-12696
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / State Backends
> Reporter: Yu Li
> Assignee: Yu Li
> Priority: Major
>
> Since we plan to use mmap to accelerate the state read/write against the
> spilled (on-disk) KeyGroup, we need a {{MmapManager}} to manage the mmap-ed
> files, pretty much like the
> [MemoryMappedFileManager|https://s.apache.org/85BP] in log4j2.
