How to set MassTransit rate limit dynamically?
问题
The translation of the code part you provided is as follows:
如何使用IPipeRouter动态设置速率限制
目前，我使用以下的UseRateLimit配置方法。但我需要动态更改速率限制。
cfg.ReceiveEndpoint("SomeEvent", x =>
{
x.UseRateLimit(1, TimeSpan.FromSeconds(1));
x.ConfigureConsumer<SomeEventConsumer>(context);
});
我看到UseRateLimit方法有一个类型为IPipeRouter的router参数。参数的解释是：
用于动态调整速率限制的控制管道。
但我找不到关于它的示例。
英文:
How can use the IPipeRouter to dynamically set the rate limit
Currently, I use UseRateLimit configuration method as following. But I need to change the rate limit dynamically.
cfg.ReceiveEndpoint("SomeEvent", x =>
{
x.UseRateLimit(1, TimeSpan.FromSeconds(1));
x.ConfigureConsumer<SomeEventConsumer>(context);
});
I see that UseRateLimit method has router parameter with type IPipeRouter.The explanation of the parameter is
> The control pipe used to adjust the rate limit dynamically.

But I couldn't find an example on it.

没有记录/支持的动态调整速率限制的方式。
有一些传统的方法允许进行此类更改，但它们的使用相对复杂（这也是为什么不支持的原因）。
var router = new PipeRouter();
cfg.UseRateLimit(100, TimeSpan.FromSeconds(1), router);
保存该管道路由器由您来决定，但在代码的其他地方，您可以调用：
await router.SetRateLimit(10);
然后可以根据您的需要进行上下调整。
再次强调，这并不受支持，但可能适用于您的情况。
英文:
There is no documented/supported way to dynamically adjust the rate limit.
There are legacy methods that allowed such a change, but the use of them is complicated (and thus why it isn't supported).
var router = new PipeRouter();
cfg.UseRateLimit(100, TimeSpan.FromSeconds(1), router);
Saving that pipe router is up to you, but somewhere else in the code, you could call:
await router.SetRateLimit(10);
And it can be adjusted up or down to suit your purpose.
> Again, this is not supported but could work for you.
