Exponential backoff with jitter retry?

[JimNero009]

Hello,

I've been seeing some intermittent TImeout errors with our Redis instance. I can't find any underlying reason why that might be, so I was just going to add a retry mechanism to our configuration (we currently have none).

Being in the AWS world a fair bit, a recommended strategy there is for an exponential backoff with jitter. I notice that in this library you have a wide range of strategies, but not that one. EqualJitterBackoff seems quite close but not exactly the same.

I was interested in why this is? Do you feel actually the range you already have cover all reasonable usecases already? In which case, would you suggest I use those over creating a new class for this (which I would be happy to contribute back)?

@JimNero009 Hi! You're right the EqualJitterBackoff is precisely what you need, but I agree it makes sense to support a combination Exponential Backoff + Jitter, feel free to contribute

Thanks Vladyslav! Expect something soon 🚀, but I think EqualJitterBackoff is perfectly fine for this particular use case I have.

#3550 for your perusal. I didn't see any direct tests for these classes, but point me to them if there is something.

@JimNero009 You're right, there's no tests for now, please create a new file test file and add coverage for your changes

@JimNero009
We started experiencing intermittent timeouts with our AWS Redis instance last week as well, and we still haven't identified the issue yet.

Merged in #3550

Thanks for being receptive to this!
