compare
compare 命令可帮助您分析两次基准测试之间的差异。这有助于您根据特定的 Git 版本分析先前测试所做更改的性能影响。
用法
您可以使用其 TestExecution ID 比较两次不同的工作负载测试。要查找特定工作负载运行的测试列表，请使用 opensearch-benchmark list test_executions。您应该会收到类似于以下内容的输出
____ _____ __ ____ __ __
/ __ \____ ___ ____ / ___/___ ____ ___________/ /_ / __ )___ ____ _____/ /_ ____ ___ ____ ______/ /__
/ / / / __ \/ _ \/ __ \\__ \/ _ \/ __ `/ ___/ ___/ __ \ / __ / _ \/ __ \/ ___/ __ \/ __ `__ \/ __ `/ ___/ //_/

然后使用 compare 命令调用一个 --baseline 测试和一个 --contender 测试进行比较。
opensearch-benchmark compare --baseline=417ed42-6671-9i79-11a1-e367636068ce --contender=beb154e4-0a05-4f45-ad9f-e34f9a9e51f7
您应该会收到以下响应，其中比较了两次测试的最终基准指标
