Time window with exponential backoff

[KaranH15]

Prerequisites

• I have written a descriptive issue title
• I have searched existing issues to ensure the feature has not already been requested

🚀 Feature Proposal

Right now in timeWindow option we can set retries for regular interval of time. There is no option for allowing exponential backoff time. E.g If I want user to retry for following time windows - 1min, 5 min, 15min ........ No option to configure that rn.

Motivation

No response

Example

No response

The current implementation do not keep how many times for an ip to be banned.
Those data would require a persistence storage other than redis.

I think the idea good, but not sure if it worth for storing such data.

Just because I have the code currently open in my vscode: Exponential back off can be implemented by the following code:

/**
 * Exponential backoff is the process of a client periodically retrying a
 * failed request over an increasing amount of time. It is a standard error
 * handling strategy for network applications. The Core Reporting API is
 * designed with the expectation that clients which choose to retry failed
 * requests do so using exponential backoff. Besides being "required", using
 * exponential backoff increases the efficiency of bandwidth usage, reduces
 * the number of requests required to get a successful response, and
 * maximizes the throughput of requests in concurrent environments.
 *
 * @see https://developers.google.com/analytics/devguides/reporting/core/v3/errors#backoff

function exponentialDelay(retryNumber) {
	const delayInSeconds = Math.pow(2, retryNumber)
	const randomMs = ~~(1000 * Math.random())
	return delayInSeconds * 1000 + randomMs
}
