arangodb - arangob 不能发送超过 1000 个请求

Question

我使用 arangob 来测试 ArangoDB 的性能，但是 arangob 不能发送超过 1000 个请求。“操作总数:”始终为 1000。

我的终端输出如下。

$./arangob --server.endpoint "tcp://127.0.0.1:8529" --delay --requests 50000  --test-case     document --complexity 10  --batch-size 0 --concurrency 1

问题似乎是由 --delay 选项引起的。当我尝试时，省略它可以解决问题。现在将研究为什么 delay 会造成麻烦。

更新:--delay 需要一个 bool 值作为它的参数，例如--延迟为真。省略参数将使命令行解析器将下一个命令行参数解释为 --delay 参数的值。在您的情况下是 --requests，因此 --requests 选项将被忽略。

所以命令行应该是:

./arangob --server.endpoint "tcp://127.0.0.1:8529" --delay true --requests 50000  --test-case document --complexity 10 --batch-size 0 --concurrency 1
