implementing retries in HystrixCommand/Fallback

[Carey Boldenow]

Hello,

In the event my HystrixCommand times out, I would like to implement the ability in my fallback to retry up to 3 times before calling it a day and returning a static response. Below is my initial cut at it, which I now know has many flaws :-)  What approach have others used to introduce a retry capability to their HystrixCommands?

@Override 

protected Person getFallback() {

retryCounter++;

if (retryCounter < 3) {

runTask();

}

return new Person (99,"Wayne","Gretzky", "superstar");

}

You can put retry logic of that sort into a "try-catch" block in the main run callback. Your fallback should be as slim as possible.

If your command had failed due to timeout, then getFallback runs on timer thread. In that case if you again call your run method, it will simply execute as normal method and it won't have any timeout or any hystrix configured threadpool values.
