[英]How to override the retry configuration for Google Cloud Tasks Node.js Client
I've been trying explore if there's a way to retry the createTask function . 我一直在尝试探索是否有办法重试createTask函数 。 The reason being is because I keep on encountering deadline exceeded error from time to time like so: 原因是因为我不时会遇到截止日期超出错误:
Error: 4 DEADLINE_EXCEEDED: Deadline Exceeded at Object.exports.createStatusError (/srv/node_modules/grpc/src/common.js:91:15) at Object.onReceiveStatus (/srv/node_modules/grpc/src/client_interceptors.js:1204:28) at InterceptingListener._callNext (/srv/node_modules/grpc/src/client_interceptors.js:568:42) at InterceptingListener.onReceiveStatus (/srv/node_modules/grpc/src/client_interceptors.js:618:8) at callback (/srv/node_modules/grpc/src/client_interceptors.js:845:24) 错误:4 DEADLINE_EXCEEDED:Object.onReceiveStatus上的Object.exports.createStatusError(/srv/node_modules/grpc/src/common.js:91:15)截止日期超过(/srv/node_modules/grpc/src/client_interceptors.js:1204 :28)在InterceptingListener._callNext(/srv/node_modules/grpc/src/client_interceptors.js:568:42)处于InterceptingListener.onReceiveStatus(/srv/node_modules/grpc/src/client_interceptors.js:618:8)的回调中( /srv/node_modules/grpc/src/client_interceptors.js:845:24)
Reading on the code behind the createTask function, I found out that the default timeout configuration was just 10 seconds. 阅读createTask函数后面的代码,我发现默认的超时配置只有10秒。
At the moment, I have tried to extend the timeout to 30s (which I believe is the maximum) by doing this: 目前,我已经尝试通过执行以下操作将超时延长到30秒(我相信这是最大值):
try {
console.log("Sending task %j", task);
const callOptions = {
timeout: 30000
};
// Send create task request.
const [response] = await client.createTask(request, callOptions);
const name = response.name;
console.log(`Created task ${name}`);
} catch (error) {
console.error("CREATE_TASK_ERROR::", error);
}
And it appears that it works. 它似乎有效。 However, I would also like to cover the case if the API wasn't able to respond within 30 seconds. 但是,如果API无法在30秒内响应,我还想了解此案例。
I've tried this code: 我试过这段代码:
try {
console.log("Sending task %j", task);
const callOptions = {
timeout: 2000, // I've set it to 2 seconds to be able to reproduce the deadline exceeded error easily
retry: {
initial_retry_delay_millis: 100,
retry_delay_multiplier: 1.3,
max_retry_delay_millis: 60000,
initial_rpc_timeout_millis: 20000,
rpc_timeout_multiplier: 1.0,
max_rpc_timeout_millis: 20000,
total_timeout_millis: 300000
}
};
// Send create task request.
const [response] = await client.createTask(request, callOptions);
const name = response.name;
console.log(`Created task ${name}`);
} catch (error) {
console.error("CREATE_TASK_ERROR::", error);
}
But I don't see the createTask being retried. 但我没有看到createTask正在重试。 But based on the comment here , we should be able to override the default settings including retries. 但根据此处的评论,我们应该能够覆盖默认设置,包括重试。
What am I doing wrong? 我究竟做错了什么? Please help. 请帮忙。
It seems to that callOptions is wrong. 似乎callOptions是错误的。
const callOptions = {
timeout: 2000, // I've set it to 2 seconds to be able to reproduce the deadline exceeded error easily
retry: {
backoffSettings: {
initialRetryDelayMillis: 100,
retryDelayMultiplier: 1.3,
maxRetryDelayMillis: 60000,
initialRpcTimeoutMillis: 20000,
// rpc_timeout_multiplier: 1.0, not exists
maxRpcTimeoutMillis: 20000,
totalTimeoutMillis: 300000
}
}
};

But I think that to set retry parameters using cli is better. 但我认为使用cli设置重试参数更好。
