Matt Sicker created KAFKA-4802: ---------------------------------- Summary: Support direct ByteBuffer serializers/deserializers in clients Key: KAFKA-4802 URL: https://issues.apache.org/jira/browse/KAFKA-4802 Project: Kafka Issue Type: New Feature Components: clients Reporter: Matt Sicker
RecordAccumulator and Fetcher are already written to take advantage of a pool of ByteBuffers, but Serializer and Deserializer require you to return a byte array. If I have a key or value format that is better handled directly via ByteBuffer, the added conversion to a byte array introduces unnecessary garbage. An example use case would be in enhancing the KafkaAppender in Log4j 2 to support garbage free logging (or minimal garbage; I haven't really looked at the entire code path). -- This message was sent by Atlassian JIRA (v6.3.15#6346)
