>             Project: Flink
>          Issue Type: Improvement
>          Components: Runtime / Network
>    Affects Versions: 1.10.0
>            Reporter: Piotr Nowojski
>            Assignee: Piotr Nowojski
>            Priority: Major

> Currently almost all interactions with the network stack are happening from the mailbox thread, except of {{org.apache.flink.runtime.io.network.api.writer.ResultPartitionWriter#flushAll}}, which happens from {{OutputFlusher}} thread.
> We could move {{ResultPartitionWriter#flushAll}} to happen in the mailbox thread (as a mailbox action), which would further simplify the threading model.
