--------------------------------------
Summary: Add a JMH benchmark to measure SCMRatisRequest and
SCMRatisResponse codec performance.
Key: HDDS-15164
URL: https://issues.apache.org/jira/browse/HDDS-15164
Project: Apache Ozone
Issue Type: Task
Reporter: Jheng-Sing Chen
Assignee: Jheng-Sing Chen
The benchmark should measure encode/decode throughput separately for request
and response paths. It should pre-generate benchmark inputs with a fixed random
seed so that the measured time focuses on codec serialization/deserialization
rather than test data generation.
Initial benchmark coverage:
- SCMRatisRequest encode
- SCMRatisRequest decode
- SCMRatisResponse encode
- SCMRatisResponse decode
- PipelineID protobuf payload
- Long payload
- List<PipelineID> payload
Benchmark configuration:
- JMH 1.37
- Throughput mode
- 5 warmup iterations
- 10 measurement iterations
- 3 forks
- 1000 pre-generated input objects
This benchmark can be used to compare SCM Ratis codec performance before and
after HDDS-14647.
