# Introduction to Sonic
## Background
According to the overall profiling of production services in Bytedance, we found that the overhead of JSON serialization and deserialization is unexpectedly high: the total is near to 10% CPU, and the extreme one accounts for more than 40% CPU. Therefore, **the performance of JSON lib is a key issue for the promotion of machine utilization**.
## Research
We conducted a series of surveys and benchmarks on open-sourced JSON libraries for Golang, but the result is disappointing: **no silver bullet**. First of all, no one can perform at least the top three across various business scenarios. Even the most widely used [json-iterator](https://github.com/json-iterator/go) will severely degrade in generic (no-schema) or big-volume JSON serialization and deserialization. Secondly, compared with other JSON libraries writing in other languages, their speed is generally much slower. For example, [Simdjson-go](https://github.com/minio/simdjson-go) has a 50% reduction in decoding performance compared to [simdjson](https://github.com/simdjson/simdjson). What's more, we barely found JSON libraries which provide API to modify the underlying values.
Therefore, we decided to **develop a brand-new JSON library with high performance as well as wide applicability**.
## Thinking
Before starting our design, we need to figure out some questions:
### Why is Json-iterator faster than Standard Library?
First of all, the **schema-based processing mechanism** used by the standard library is commendable, in which the parser can obtain meta information in advance when scanning, thereby shortening the time of branch selection. However, its original implementation did not make good use of this mechanism, instead, **it spent a lot of time reflecting to obtain meta info of schema**. Meanwhile, The approach of json-iterator is: Interprete structure as field-by-field encoding and decoding functions, and then assembled and cached them, minimizing the performance loss cost by reflection. But does it work once and for all? No. In practical tests, we found that **the deeper and larger the input JSON got, the smaller the gap between json-iterator and other libraries gradually became** - eventually event got surpassed:
![Scalability](introduction-1.png)
The reason is that **this implementation transforms into a large number of interface encapsulations and function calls**, followed by function-call losses:
1. **Calling interface involves dynamic addressing of itab**
2. **Assembly functions cannot be inlined**, while Golang's function-call performance is poor (no parameter-passing-by-register)
#### Is there a way to avoid the function-call overhead of dynamic assembly?
The first thing we thought about was code generation like [easyjson](https://github.com/mailru/easyjson). But it comes with **schema dependency and convenience losses**. To achieve a real drop-in replacement of the standard library, we turned to another technology - **[JIT](https://en.wikipedia.org/wiki/Jit) (just-in-time compiling)**. Because the compiled codec function is an integrated function, which can greatly reduce function calls while ensuring flexibility.
### Why is Simdjson-go not fast enough?
[SIMD](https://en.wikipedia.org/wiki/SIMD) (Single-Instruction-Multi-Data) is a special set of CPU instructions for the parallel processing of vectorized data. At present, it is supported by most CPUs and widely used in image processing and big data computing. Undoubtedly, SIMD is useful in JSON processing (itoa, char-search and so on are all suitable scenarios). We can see that simdjson-go is very competitive in large JSON scenarios (>100KB). However, for some extremely small or irregular character strings, **the extra load operation required by SIMD will lead to performance degradation**. Therefore, we need to dedicate ourselves to branch predicting and decide which scenarios should use SIMD and which should not (for example, the string length is less than 16 bytes).
The second problem comes from the Go compiler itself. In order to ensure the compilation speed, **Golang does very little optimization work during the compilation phase** and cannot directly use compiler backends such as [LLVM](https://en.wikipedia.org/wiki/LLVM) (Low-Level Virtual Machine) for optimization.
So, **can some crucial calculation functions be written in another language with higher execution efficiency**?
C/Clang is an ideal compilation tool (internal integration LLVM). But the key is how to embed the optimized assembly into Golang.
### How to use Gjson well?
We also found that [gjson](https://github.com/tidwall/gjson) has a huge advantage in single-key lookup scenarios. This is because its lookup is implemented by a **lazy-load mechanism**, which subtlely skips passing-by values and effectively reduces a lot of unnecessary parsing. Practical application has proved that making good use of this feature in product can indeed bring benefits. But when it comes to multi-key lookup, Gjson does worse event than std, which is a side effect of its skipping mechanism - **searching for the same path leads to repeated parsing** (skip is also a lightweight parsing). Therefore, the accurate adaptation of practical scenarios is the key.
## Design
Based on the above questions, our design is easy to implement:
1. Aiming at the function-call overhead cost by the codec dynamic-assembly, **`JIT` tech is used to assemble opcodes (asm) corresponding to the schema at runtime**, which is finally cached into the off-heap memory in the form of Golang functions.
2. For practical scenarios where big data and small data coexist, we **use pre-conditional judgment** (string size, floating precision, etc.) **to combine `SIMD` with scalar instructions** to achieve the best adaptation.
3. As for insufficiency in compiling optimization of go language, we decided to **use `C/Clang` to write and compile core computational functions**, and **developed a set of [asm2asm](https://github.com/chenzhuoyu/asm2asm) tools to translate the fully optimized x86 assembly into plan9** and finally load it into Golang runtime.
4. Giving the big speed gap between parsing and skipping, the **`lazy-load` mechanism** is certainly used in our AST parser, but in **a more adaptive and efficient way to reduce the overhead of multiple-key queries**.
![design](introduction-2.png)
In detail, we conducted some further optimization:
1. Since the native-asm functions cannot be inlined in Golang, we found that its cost even exceeded the improvement brought by the optimization of the C compiler. So we reimplemented a set of lightweight function-calls in JIT:
- `Global-function-table + static offset` for calling instruction
- **Pass parameters using registers**
2. `Sync.Map` was used to cache the codecs at first, but for our **quasi-static** (read far more than write), **fewer elements** (usually no more than a few dozen) scenarios, its performance is not optimal, so we reimplement a high-performance and concurrent-safe cache with `open-addressing-hash + RCU` tech.

## 工作原理
请参阅 [INTRODUCTION_ZH_CN.md](./docs/INTRODUCTION_ZH_CN.md).
## 使用方式
### 序列化/反序列化
默认的行为基本上与 `encoding/json` 相一致,除了 HTML 转义形式(参见 [Escape HTML](https://github.com/bytedance/sonic/blob/main/README.md#escape-html)) 和 `SortKeys` 功能(参见 [Sort Keys](https://github.com/bytedance/sonic/blob/main/README.md#sort-keys)**没有**遵循 [RFC8259](https://datatracker.ietf.org/doc/html/rfc8259) 。
```go
import "github.com/bytedance/sonic"
var data YourSchema
// Marshal
output, err := sonic.Marshal(&data)
// Unmarshal
err := sonic.Unmarshal(output, &data)
```
### 流式输入输出
Sonic 支持解码 `io.Reader` 中输入的 json或将对象编码为 json 后输出至 `io.Writer`,以处理多个值并减少内存消耗。
- 编码器
```go
var o1 = map[string]interface{}{
"a": "b",
}
var o2 = 1
var w = bytes.NewBuffer(nil)
var enc = sonic.ConfigDefault.NewEncoder(w)
enc.Encode(o1)
enc.Encode(o2)
fmt.Println(w.String())
// Output:
// {"a":"b"}
// 1
```
- 解码器
```go
var o = map[string]interface{}{}
var r = strings.NewReader(`{"a":"b"}{"1":"2"}`)
var dec = sonic.ConfigDefault.NewDecoder(r)
dec.Decode(&o)
dec.Decode(&o)
fmt.Printf("%+v", o)
// Output:
// map[1:2 a:b]
```
### 使用 `Number` / `int64`
```go
import "github.com/bytedance/sonic/decoder"
var input = `1`
var data interface{}
// default float64
dc := decoder.NewDecoder(input)
dc.Decode(&data) // data == float64(1)
// use json.Number
dc = decoder.NewDecoder(input)
dc.UseNumber()
dc.Decode(&data) // data == json.Number("1")
// use int64
dc = decoder.NewDecoder(input)
dc.UseInt64()
dc.Decode(&data) // data == int64(1)
root, err := sonic.GetFromString(input)
// Get json.Number
jn := root.Number()
jm := root.InterfaceUseNumber().(json.Number) // jn == jm
// Get float64
fn := root.Float64()
fm := root.Interface().(float64) // jn == jm
```
### 对键排序
考虑到排序带来的性能损失(约 10% sonic 默认不会启用这个功能。如果你的组件依赖这个行为(如 [zstd](https://github.com/facebook/zstd)) ,可以仿照下面的例子:
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/encoder"
// Binding map only
m := map[string]interface{}{}
v, err := encoder.Encode(m, encoder.SortMapKeys)
// Or ast.Node.SortKeys() before marshal
var root := sonic.Get(JSON)
err := root.SortKeys()
```
### HTML 转义
考虑到性能损失约15% sonic 默认不会启用这个功能。你可以使用 `encoder.EscapeHTML` 选项来开启(与 `encoding/json.HTMLEscape` 行为一致)。
```go
import "github.com/bytedance/sonic"
v := map[string]string{"&&":"<>"}
ret, err := Encode(v, EscapeHTML) // ret == `{"\u0026\u0026":{"X":"\u003c\u003e"}}`
```
### 紧凑格式
Sonic 默认将基本类型( `struct` `map` 等)编码为紧凑格式的 JSON ,除非使用 `json.RawMessage` or `json.Marshaler` 进行编码: sonic 确保输出的 JSON 合法,但出于性能考虑,**不会**加工成紧凑格式。我们提供选项 `encoder.CompactMarshaler` 来添加此过程,
### 打印错误
如果输入的 JSON 存在无效的语法sonic 将返回 `decoder.SyntaxError`,该错误支持错误位置的美化输出。
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/decoder"
var data interface{}
err := sonic.UnmarshalString("[[[}]]", &data)
if err != nil {
/* One line by default */
println(e.Error()) // "Syntax error at index 3: invalid char\n\n\t[[[}]]\n\t...^..\n"
/* Pretty print */
if e, ok := err.(decoder.SyntaxError); ok {
/*Syntax error at index 3: invalid char
[[[}]]
...^..
*/
print(e.Description())
} else if me, ok := err.(*decoder.MismatchTypeError); ok {
// decoder.MismatchTypeError is new to Sonic v1.6.0
print(me.Description())
}
}
```
#### 类型不匹配 [Sonic v1.6.0]
如果给定键中存在**类型不匹配**的值, sonic 会抛出 `decoder.MismatchTypeError` (如果有多个,只会报告最后一个),但仍会跳过错误的值并解码下一个 JSON 。
```go
import "github.com/bytedance/sonic"
import "github.com/bytedance/sonic/decoder"
var data = struct{
A int
B int
}{}
err := UnmarshalString(`{"A":"1","B":1}`, &data)
println(err.Error()) // Mismatch type int with value string "at index 5: mismatched type with value\n\n\t{\"A\":\"1\",\"B\":1}\n\t.....^.........\n"
fmt.Printf("%+v", data) // {A:0 B:1}
```
### `Ast.Node`
Sonic/ast.Node 是完全独立的 JSON 抽象语法树库。它实现了序列化和反序列化,并提供了获取和修改通用数据的鲁棒的 API。
#### 查找/索引
通过给定的路径搜索 JSON 片段,路径必须为非负整数,字符串或 `nil`
```go
import "github.com/bytedance/sonic"
input := []byte(`{"key1":[{},{"key2":{"key3":[1,2,3]}}]}`)
// no path, returns entire json
root, err := sonic.Get(input)
raw := root.Raw() // == string(input)
// multiple paths
root, err := sonic.Get(input, "key1", 1, "key2")
sub := root.Get("key3").Index(2).Int64() // == 3
```
**注意**:由于 `Index()` 使用偏移量来定位数据,比使用扫描的 `Get()` 要快的多,建议尽可能的使用 `Index` 。 Sonic 也提供了另一个 API `IndexOrGet()` ,以偏移量为基础并且也确保键的匹配。
#### 修改
使用 ` Set()` / `Unset()` 修改 json 的内容
```go
import "github.com/bytedance/sonic"
// Set
exist, err := root.Set("key4", NewBool(true)) // exist == false
alias1 := root.Get("key4")
println(alias1.Valid()) // true
alias2 := root.Index(1)
println(alias1 == alias2) // true
// Unset
exist, err := root.UnsetByIndex(1) // exist == true
println(root.Get("key4").Check()) // "value not exist"
```
#### 序列化
要将 `ast.Node` 编码为 json ,使用 `MarshalJson()` 或者 `json.Marshal()` (必须传递指向节点的指针)
```go
import (
"encoding/json"
"github.com/bytedance/sonic"
)
buf, err := root.MarshalJson()
println(string(buf)) // {"key1":[{},{"key2":{"key3":[1,2,3]}}]}
exp, err := json.Marshal(&root) // WARN: use pointer
println(string(buf) == string(exp)) // true
```
#### APIs
- 合法性检查: `Check()`, `Error()`, `Valid()`, `Exist()`
- 索引: `Index()`, `Get()`, `IndexPair()`, `IndexOrGet()`, `GetByPath()`
- 转换至 go 内置类型: `Int64()`, `Float64()`, `String()`, `Number()`, `Bool()`, `Map[UseNumber|UseNode]()`, `Array[UseNumber|UseNode]()`, `Interface[UseNumber|UseNode]()`
- go 类型打包: `NewRaw()`, `NewNumber()`, `NewNull()`, `NewBool()`, `NewString()`, `NewObject()`, `NewArray()`
- 迭代: `Values()`, `Properties()`, `ForEach()`, `SortKeys()`
- 修改: `Set()`, `SetByIndex()`, `Add()`
## 兼容性
由于开发高性能代码的困难性, Sonic **不**保证对所有环境的支持。对于在不同环境中使用 Sonic 构建应用程序的开发者,我们有以下建议:
- 在 **Mac M1** 上开发:确保在您的计算机上安装了 Rosetta 2并在构建时设置 `GOARCH=amd64` 。 Rosetta 2 可以自动将 x86 二进制文件转换为 arm64 二进制文件,并在 Mac M1 上运行 x86 应用程序。
- 在 **Linux arm64** 上开发:您可以安装 qemu 并使用 `qemu-x86_64 -cpu max` 命令来将 x86 二进制文件转换为 arm64 二进制文件。qemu可以实现与Mac M1上的Rosetta 2类似的转换效果。
对于希望在不使用 qemu 下使用 sonic 的开发者,或者希望处理 JSON 时与 `encoding/JSON` 严格保持一致的开发者,我们在 `sonic.API` 中提供了一些兼容性 API
- `ConfigDefault`: 在支持 sonic 的环境下 sonic 的默认配置(`EscapeHTML=false``SortKeys=false`等)。行为与具有相应配置的 `encoding/json` 一致,一些选项,如 `SortKeys=false` 将无效。
- `ConfigStd`: 在支持 sonic 的环境下与标准库兼容的配置(`EscapeHTML=true``SortKeys=true`等)。行为与 `encoding/json` 一致。
- `ConfigFastest`: 在支持 sonic 的环境下运行最快的配置(`NoQuoteTextMarshaler=true`)。行为与具有相应配置的 `encoding/json` 一致,某些选项将无效。
## 注意事项
### 预热
由于 Sonic 使用 [golang-asm](https://github.com/twitchyliquid64/golang-asm) 作为 JIT 汇编器,这个库并不适用于运行时编译,第一次运行一个大型模式可能会导致请求超时甚至进程内存溢出。为了更好地稳定性,我们建议在运行大型模式或在内存有限的应用中,在使用 `Marshal()/Unmarshal()` 前运行 `Pretouch()`
```go
import (
"reflect"
"github.com/bytedance/sonic"
"github.com/bytedance/sonic/option"
)
func init() {
var v HugeStruct
// For most large types (nesting depth <= option.DefaultMaxInlineDepth)
err := sonic.Pretouch(reflect.TypeOf(v))
// with more CompileOption...
err := sonic.Pretouch(reflect.TypeOf(v),
// If the type is too deep nesting (nesting depth > option.DefaultMaxInlineDepth),
// you can set compile recursive loops in Pretouch for better stability in JIT.
option.WithCompileRecursiveDepth(loop),
// For a large nested struct, try to set a smaller depth to reduce compiling time.
option.WithCompileMaxInlineDepth(depth),
)
}
```
### 拷贝字符串
当解码 **没有转义字符的字符串**时, sonic 会从原始的 JSON 缓冲区内引用而不是复制到新的一个缓冲区中。这对 CPU 的性能方面很有帮助,但是可能因此在解码后对象仍在使用的时候将整个 JSON 缓冲区保留在内存中。实践中我们发现,通过引用 JSON 缓冲区引入的额外内存通常是解码后对象的 20% 至 80% ,一旦应用长期保留这些对象(如缓存以备重用),服务器所使用的内存可能会增加。我们提供了选项 `decoder.CopyString()` 供用户选择,不引用 JSON 缓冲区。这可能在一定程度上降低 CPU 性能。
### 传递字符串还是字节数组?
为了和 `encoding/json` 保持一致,我们提供了传递 `[]byte` 作为参数的 API ,但考虑到安全性,字符串到字节的复制是同时进行的,这在原始 JSON 非常大时可能会导致性能损失。因此,你可以使用 `UnmarshalString()``GetFromString()` 来传递字符串,只要你的原始数据是字符串,或**零拷贝类型转换**对于你的字节数组是安全的。我们也提供了 `MarshalString()` 的 API ,以便对编码的 JSON 字节数组进行**零拷贝类型转换**,因为 sonic 输出的字节始终是重复并且唯一的,所以这样是安全的。
### 加速 `encoding.TextMarshaler`
为了保证数据安全性, `sonic.Encoder` 默认会对来自 `encoding.TextMarshaler` 接口的字符串进行引用和转义,如果大部分数据都是这种形式那可能会导致很大的性能损失。我们提供了 `encoder.NoQuoteTextMarshaler` 选项来跳过这些操作,但你**必须**保证他们的输出字符串依照 [RFC8259](https://datatracker.ietf.org/doc/html/rfc8259) 进行了转义和引用。
### 泛型的性能优化
在 **完全解析**的场景下, `Unmarshal()` 表现得比 `Get()`+`Node.Interface()` 更好。但是如果你只有特定 JSON 的部分模式,你可以将 `Get()``Unmarshal()` 结合使用:
```go
import "github.com/bytedance/sonic"
node, err := sonic.GetFromString(_TwitterJson, "statuses", 3, "user")
var user User // your partial schema...
err = sonic.UnmarshalString(node.Raw(), &user)
```
甚至如果你没有任何模式,可以用 `ast.Node` 代替 `map``interface` 作为泛型的容器:
```go
import "github.com/bytedance/sonic"
root, err := sonic.GetFromString(_TwitterJson)
user := root.GetByPath("statuses", 3, "user") // === root.Get("status").Index(3).Get("user")
err = user.Check()
// err = user.LoadAll() // only call this when you want to use 'user' concurrently...
go someFunc(user)
```
为什么?因为 `ast.Node` 使用 `array` 来存储其子节点:
- 在插入(反序列化)和扫描(序列化)数据时,`Array` 的性能比 `Map` **好得多**
- **哈希**`map[x]`)的效率不如**索引**`array[x]`)高效,而 `ast.Node` 可以在数组和对象上使用索引;
- 使用 `Interface()` / `Map()` 意味着 sonic 必须解析所有的底层值,而 `ast.Node` 可以**按需解析**它们。
**注意**:由于 `ast.Node` 的惰性加载设计,其**不能**直接保证并发安全性,但你可以调用 `Node.Load()` / `Node.LoadAll()` 来实现并发安全。尽管可能会带来性能损失,但仍比转换成 `map``interface{}` 更为高效。
