Backoff policies

The @daiso-tech/core/backoff-policies component

Predefined backoff policies

The library includes predefined backoff policies:

• constantBackoff - Constant backoff policy with jitter

import { TimeSpan } from "@daiso-tech/core/time-span";
import { constantBackoff } from "@daiso-tech/core/backoff-policies";

// The settings argument is optional and all its fields are optional
const backoff = constantBackoff({
    delay: TimeSpan.fromSeconds(1),
    jitter: 0.5, // You can pass null to disable jitter
});

• exponentialBackoff - Exponential backoff policy with jitter

import { TimeSpan } from "@daiso-tech/core/time-span";
import { exponentialBackoff } from "@daiso-tech/core/backoff-policies";

// The settings argument is optional and all its fields are optional
const backoff = exponentialBackoff({
    maxDelay: TimeSpan.fromSeconds(60),
    minDelay: TimeSpan.fromMilliseconds(500),
    multiplier: 2,
    jitter: 0.5, // You can pass null to disable jitter
});

• linearBackoff - Linear backoff policy with jitter

import { TimeSpan } from "@daiso-tech/core/time-span";
import { linearBackoff } from "@daiso-tech/core/backoff-policies";

// The settings argument is optional and all its fields are optional
const backoff = linearBackoff({
    maxDelay: TimeSpan.fromSeconds(60),
    minDelay: TimeSpan.fromMilliseconds(500),
    jitter: 0.5, // You can pass null to disable jitter
});

• polynomialBackoff - Polynomial backoff policy with jitter

import { TimeSpan } from "@daiso-tech/core/time-span";
import { linearBackoff } from "@daiso-tech/core/backoff-policies";

// The settings argument is optional and all its fields are optional
const backoff = linearBackoff({
    maxDelay: TimeSpan.fromSeconds(60),
    minDelay: TimeSpan.fromMilliseconds(500),
    degree: 2,
    jitter: 0.5, // You can pass null to disable jitter
});
