Seriallel

Seriallel attempts to increase the performance of serializing large data structures to JSON. Namely, when an array or slice is encountered, each item is serialized in its own goroutine.

Getting Started

package main

import "github.com/blakearoberts/seriallel/json"

type Big struct {
    // ...
}

func main() {
    bigs := []Big{/* ... */}
    bytes, err := json.Marshal(bigs)
    if err != nil {
        panic(err)
    }
    println(string(bytes))
}

Performance

Really bad.

In practice, I was able to reduce serialization time from ~40ms to ~15ms for ~512KB payloads where the data structure resembled the following:

[
    {
        "field": [
            {},
            ..., m // m ~ 10
        ],
        ...,
    },
    ..., n // n ~ 20
]
