[jira] [Created] (FLINK-5060) only serialise records once in
RecordWriter#emit and RecordWriter#broadcastEmit
Nico Kruber created FLINK-5060:
----------------------------------
Summary: 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
Assignee: Nico Kruber
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.
