----------------------------------
Summary: only serialise events once in RecordWriter#broadcastEvent
Key: FLINK-5059
URL: https://issues.apache.org/jira/browse/FLINK-5059
Project: Flink
Issue Type: Improvement
Components: Network
Reporter: Nico Kruber
Assignee: Nico Kruber
Currently,
org.apache.flink.runtime.io.network.api.writer.RecordWriter#broadcastEvent
serialises the event once per target channel. Instead, it could serialise the
event only once and use the serialised form for every channel and thus save
resources.
