simdjson-go VS jsonparser

Speaking of Go, there's a simdjson implementation for golang too:

> Performance wise, simdjson-go runs on average at about 40% to 60% of the speed of simdjson. Compared to Golang's standard package encoding/json, simdjson-go is about 10x faster.

I haven't tried it yet but I don't really need that speed.

I agree. For performance-sensitive situations, C/C++ or Rust is the only choice. However, many developers choose Go or other languages for engineering efficiency. A typical use case of SIMD in Go is simdjson-go. Besides, there are plenty of bindings and ports of simdjson. "Other languages" developers also need performance improvement from native instructions such as SIMD.

I suggest to use a streaming library to parse your file. Like jstream or simdjson-go

You can also try comparing with https://github.com/minio/simdjson-go. It does use a different API, however, would be good to compare nevertheless.

In this article, I will introduce you to a new package called astjson that I have been working on for the last couple of weeks. It is a Go package that allows you to transform and merge JSON objects with unmatched speed. It is based on the jsonparser package by buger aka Leonid Bugaev and extends it with the ability to transform and merge JSON objects at unparalleled performance.

Use this to extract the data value, and handle/unmarshal it accordingly.

jsonparser can decode, but can't encode

Best I've found is this: https://github.com/buger/jsonparser

I was actually just trying to get it into a []byte to use this package which claims it works well for unknown data structures.

`jj` is a little tool I wrote that uses https://github.com/buger/jsonparser

If you don't know the schema or you only need to access one or two fields in a much larger JSON object, I would recommend https://github.com/buger/jsonparser as it provides an easy API to access specific values without fully unmarshaling. This is an unusual use case though, 9 times out of 10 I would tend to use easyjson.

Reading and navigating arbitrary JSON: I've used https://github.com/tidwall/gjson, many others like https://github.com/buger/jsonparser are also out there.
