zhijiang created FLINK-15963: -------------------------------- Summary: Reuse the same ByteBuf while writing the BufferResponse header Key: FLINK-15963 URL: https://issues.apache.org/jira/browse/FLINK-15963 Project: Flink Issue Type: Improvement Components: Runtime / Network Reporter: zhijiang
On sender side while writing the BufferResponse message, it always allocates the new direct ByteBuf from netty allocator to write header part for every message. Considering only one message is written in one channel at the same time, then we can make use of a fixed ByteBuf to write header part for all the BufferResponse messages. We can verify how it effects the performance in practice/benchmark. -- This message was sent by Atlassian Jira (v8.3.4#803005)
