---------------------------------------
Summary: Avoid additional copies in envelope path when
transmitting over network
Key: KAFKA-10684
URL: https://issues.apache.org/jira/browse/KAFKA-10684
Project: Kafka
Issue Type: Improvement
Reporter: Jason Gustafson
Assignee: Jason Gustafson
When we send an envelope request or response, we first allocate a buffer for
the embedded data. When we are ready to transmit the data, we allocate a new
buffer for the full envelope and copy the embedded data to it. We can skip the
second copy if we are a little smarter when translating the envelope data to
the network `Send` object.
