--------------------------------------
Summary: Use ByteBufferOutputStream to avoid array copy
Key: KAFKA-16397
URL: https://issues.apache.org/jira/browse/KAFKA-16397
Project: Kafka
Issue Type: Improvement
Reporter: Chia-Ping Tsai
from https://github.com/apache/kafka/pull/15148#discussion_r1531889679
source code:
https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/telemetry/internals/ClientTelemetryUtils.java#L216
we can use ByteBufferOutputStream to collect the uncompressed data, and then
return the inner buffer directly instead of copying full array.
