-----------------------------------
Summary: Allow I/O spill file writers to work with
futures/callbacks
Key: FLINK-1232
URL: https://issues.apache.org/jira/browse/FLINK-1232
Project: Flink
Issue Type: Sub-task
Components: Local Runtime
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 0.8-incubating
To simplify the implementation of the adaptive memory management, the
asynchronous writers could use callbacks that are invoked when a memory has
been successfully written.
In the current solution, the thread writing memory segments to disk needs to
keep track of how much was spilled and release that memory later.
The callbacks can in that case release the memory directly. This is both
simpler and less prone to leaks.
