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.fromSeconds(1),
    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(6),
    minDelay: TimeSpan.fromSeconds(1),
    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.fromSeconds(1),
    degree: 2,
    jitter: 0.5 // You can pass null to disable jitter
})
