Evgeny Veretennikov created KAFKA-6161:
------------------------------------------
Summary: Make configure() and close() empty by default in serde
interfaces
Key: KAFKA-6161
URL: https://issues.apache.org/jira/browse/KAFKA-6161
Project: Kafka
Issue Type: Improvement
Components: clients
Reporter: Evgeny Veretennikov
Assignee: Evgeny Veretennikov
Priority: Normal
{{Serializer}}, {{Deserializer}} and {{Serde}} interfaces have methods
{{configure()}} and {{close()}}. Pretty often one want to leave these methods
empty. For example, a lot of serializers inside
{{org.apache.kafka.common.serialization}} package have these methods empty:
{code}
@Override
public void configure(Map<String, ?> configs, boolean isKey) {
// nothing to do
}
@Override
public void close() {
// nothing to do
}
{code}
Since we switched to source level 1.8 for javac, we can make these methods
empty by default.
As another option, we may create new interfaces (like
{{UnconfiguredSerializer}}), in which we will define these methods empty, but
just making methods default seems more convenient.
As a side note, making methods default shouldn't be binary incompatible. So,
seems like it's safe to make this change.
