-----------------------------------
Summary: Fix unnecessary flush requests to the network stack
Key: FLINK-10331
URL: https://issues.apache.org/jira/browse/FLINK-10331
Project: Flink
Issue Type: Sub-task
Components: Network
Affects Versions: 1.6.0, 1.5.3, 1.5.2, 1.5.1, 1.5.0, 1.7.0
Reporter: Nico Kruber
Assignee: Nico Kruber
With the re-design of the record writer interaction with the
result(sub)partitions, flush requests can currently pile up in these scenarios_
- a previous flush request has not been handled yet and is still enqueued or
- the network stack is still polling from this subpartition and doesn't need a
new notification
These lead to increased notifications in low latency settings (low output
flusher intervals) which can be avoided.
