Resolution: Duplicate
Assignee: (was: Nico Kruber)
> only serialise records once in RecordWriter#emit and
> RecordWriter#broadcastEmit
> -------------------------------------------------------------------------------
>
> Key: FLINK-5060
> URL: https://issues.apache.org/jira/browse/FLINK-5060
> Project: Flink
> Issue Type: Improvement
> Components: Network
> Reporter: Nico Kruber
> Priority: Major
>
> Currently, org.apache.flink.runtime.io.network.api.writer.RecordWriter#emit
> and org.apache.flink.runtime.io.network.api.writer.RecordWriter#broadcastEmit
> serialise a record once per target channel. Instead, they could serialise the
> record only once and use the serialised form for every channel and thus save
> resources.
