deserializer#deserialize() in LegacyFetcher#SimpleConsumerThread#run()
Ted Yu created FLINK-3210:
-----------------------------
Summary: Unnecessary call to deserializer#deserialize() in LegacyFetcher#SimpleConsumerThread#run()
Key: FLINK-3210
URL: https://issues.apache.org/jira/browse/FLINK-3210
Project: Flink
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
Here is related code:
{code}
byte[] valueBytes;
if (payload == null) {
deletedMessages++;
valueBytes = null;
} else {
...
final T value = deserializer.deserialize(keyBytes, valueBytes, fp.topic, offset);
{code}
When valueBytes is null, there is no need to call deserializer#deserialize()
