vespa - 在 vespa 中启动和停止服务

Question

在基准测试页面“https://docs.vespa.ai/en/performance/vespa-benchmarking.html”中，我们需要在使用命令 vespa-stop 增加 persearch 线程后重新启动服务-services 和 vespa-start-services。 您能否告诉我们是否需要在所有内容节点或仅配置节点上执行此操作？

Answer 1

部署需要重启的更改时，部署命令将列出您需要执行的操作。例如，在以下示例中，将每个搜索线程的全局设置从 2 更改为 5 时:

curl --header Content-Type:application/zip --data-binary @target/application.zip   localhost:19071/application/v2/tenant/default/prepareandactivate |jq .

        }

        ],

        "reindex": []
    }
