# 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:
|
||||
|
||||
|
||||
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**.
|
||||
|
||||
|
||||
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.

negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.

9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|

License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

See [bench.sh](https://github.com/bytedance/sonic/blob/main/bench.sh) for benchmark codes.
|
||||
|
||||
## How it works
|
||||
See [INTRODUCTION.md](INTRODUCTION.md).
|
||||
|
||||
## Usage
|
||||
|
||||
### Marshal/Unmarshal
|
||||
|
||||
Default behaviors are mostly consistent with `encoding/json`, except HTML escaping form (see [Escape HTML](https://github.com/bytedance/sonic/blob/main/README.md#escape-html)) and `SortKeys` feature (optional support see [Sort Keys](https://github.com/bytedance/sonic/blob/main/README.md#sort-keys)) that is **NOT** in conformity to [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)
|
||||
```
|
||||
|
||||
### Streaming IO
|
||||
Sonic supports decoding json from `io.Reader` or encoding objects into `io.`Writer`, aims at handling multiple values as well as reducing memory consumption.
|
||||
- encoder
|
||||
```go
|
||||
import "github.com/bytedance/sonic/encoder"
|
||||
|
||||
var o1 = map[string]interface{}{
|
||||
"a": "b",
|
||||
}
|
||||
var o2 = 1
|
||||
var w = bytes.NewBuffer(nil)
|
||||
var enc = encoder.NewStreamEncoder(w)
|
||||
enc.Encode(o1)
|
||||
enc.Encode(o2)
|
||||
println(w.String()) // "{"a":"b"}\n1"
|
||||
```
|
||||
- decoder
|
||||
```go
|
||||
import "github.com/bytedance/sonic/decoder"
|
||||
|
||||
var o = map[string]interface{}{}
|
||||
var r = strings.NewReader(`{"a":"b"}{"1":"2"}`)
|
||||
var dec = decoder.NewStreamDecoder(r)
|
||||
dec.Decode(&o)
|
||||
dec.Decode(&o)
|
||||
fmt.Printf("%+v", o) // map[1:2 a:b]
|
||||
```
|
||||
|
||||
### Use Number/Use 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
|
||||
```
|
||||
|
||||
### Sort Keys
|
||||
On account of the performance loss from sorting (roughly 10%), sonic doesn't enable this feature by default. If your component depends on it to work (like [zstd](https://github.com/facebook/zstd)), Use it like this:
|
||||
```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()
|
||||
```
|
||||
### Escape HTML
|
||||
On account of the performance loss (roughly 15%), sonic doesn't enable this feature by default. You can use `encoder.EscapeHTML` option to open this feature (align with `encoding/json.HTMLEscape`).
|
||||
```go
|
||||
import "github.com/bytedance/sonic"
|
||||
|
||||
v := map[string]string{"&&":"<>"}
|
||||
ret, err := Encode(v, EscapeHTML) // ret == `{"\u0026\u0026":{"X":"\u003c\u003e"}}`
|
||||
```
|
||||
### Compact Format
|
||||
Sonic encodes primitive objects (struct/map...) as compact-format JSON by default, except marshaling `json.RawMessage` or `json.Marshaler`: sonic ensures validating their output JSON but **DONOT** compacting them for performance concerns. We provide the option `encoder.CompactMarshaler` to add compacting process.
|
||||
|
||||
### Print Error
|
||||
If there invalid syntax in input JSON, sonic will return `decoder.SyntaxError`, which supports pretty-printing of error position
|
||||
```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())
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Mismatched Types [Sonic v1.6.0]
|
||||
If there a **mismatch-typed** value for a given key, sonic will report `decoder.MismatchTypeError` (if there are many, report the last one), but still skip wrong the value and keep decoding next 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 is a completely self-contained AST for JSON. It implements serialization and deserialization both and provides robust APIs for obtaining and modification of generic data.
|
||||
#### Get/Index
|
||||
Search partial JSON by given paths, which must be non-negative integer or string, or 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
|
||||
```
|
||||
**Tip**: since `Index()` uses offset to locate data, which is much faster than scanning like `Get()`, we suggest you use it as much as possible. And sonic also provides another API `IndexOrGet()` to underlying use offset as well as ensure the key is matched.
|
||||
|
||||
#### Set/Unset
|
||||
Modify the json content by Set()/Unset()
|
||||
```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"
|
||||
```
|
||||
|
||||
#### Serialize
|
||||
To encode `ast.Node` as json, use `MarshalJson()` or `json.Marshal()` (MUST pass the node's pointer)
|
||||
```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
|
||||
- validation: `Check()`, `Error()`, `Valid()`, `Exist()`
|
||||
- searching: `Index()`, `Get()`, `IndexPair()`, `IndexOrGet()`, `GetByPath()`
|
||||
- go-type casting: `Int64()`, `Float64()`, `String()`, `Number()`, `Bool()`, `Map[UseNumber|UseNode]()`, `Array[UseNumber|UseNode]()`, `Interface[UseNumber|UseNode]()`
|
||||
- go-type packing: `NewRaw()`, `NewNumber()`, `NewNull()`, `NewBool()`, `NewString()`, `NewObject()`, `NewArray()`
|
||||
- iteration: `Values()`, `Properties()`, `ForEach()`, `SortKeys()`
|
||||
- modification: `Set()`, `SetByIndex()`, `Add()`
|
||||
|
||||
## Compatibility
|
||||
Sonic **DOES NOT** ensure to support all environments, due to the difficulty of developing high-performance codes. For developers who use sonic to build their applications in different environments, we have the following suggestions:
|
||||
|
||||
- Developing on **Mac M1**: Make sure you have Rosetta 2 installed on your machine, and set `GOARCH=amd64` when building your application. Rosetta 2 can automatically translate x86 binaries to arm64 binaries and run x86 applications on Mac M1.
|
||||
- Developing on **Linux arm64**: You can install qemu and use the `qemu-x86_64 -cpu max` command to convert x86 binaries to amr64 binaries for applications built with sonic. The qemu can achieve a similar transfer effect to Rosetta 2 on Mac M1.
|
||||
|
||||
For developers who want to use sonic on Linux arm64 without qemu, or those who want to handle JSON strictly consistent with `encoding/json`, we provide some compatible APIs as `sonic.API`
|
||||
- `ConfigDefault`: the sonic's default config (`EscapeHTML=false`,`SortKeys=false`...) to run on sonic-supporting environment. It will fall back to `encoding/json` with the corresponding config, and some options like `SortKeys=false` will be invalid.
|
||||
- `ConfigStd`: the std-compatible config (`EscapeHTML=true`,`SortKeys=true`...) to run on sonic-supporting environment. It will fall back to `encoding/json`.
|
||||
- `ConfigFastest`: the fastest config (`NoQuoteTextMarshaler=true`) to run on sonic-supporting environment. It will fall back to `encoding/json` with the corresponding config, and some options will be invalid.
|
||||
|
||||
## Tips
|
||||
|
||||
### Pretouch
|
||||
Since Sonic uses [golang-asm](https://github.com/twitchyliquid64/golang-asm) as a JIT assembler, which is NOT very suitable for runtime compiling, first-hit running of a huge schema may cause request-timeout or even process-OOM. For better stability, we advise **using `Pretouch()` for huge-schema or compact-memory applications** before `Marshal()/Unmarshal()`.
|
||||
```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),
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
### Copy string
|
||||
When decoding **string values without any escaped characters**, sonic references them from the origin JSON buffer instead of mallocing a new buffer to copy. This helps a lot for CPU performance but may leave the whole JSON buffer in memory as long as the decoded objects are being used. In practice, we found the extra memory introduced by referring JSON buffer is usually 20% ~ 80% of decoded objects. Once an application holds these objects for a long time (for example, cache the decoded objects for reusing), its in-use memory on the server may go up. We provide the option `decoder.CopyString()` for users to choose not to reference the JSON buffer, which may cause a decline in CPU performance to some degree.
|
||||
|
||||
### Pass string or []byte?
|
||||
For alignment to `encoding/json`, we provide API to pass `[]byte` as an argument, but the string-to-bytes copy is conducted at the same time considering safety, which may lose performance when the origin JSON is huge. Therefore, you can use `UnmarshalString()` and `GetFromString()` to pass a string, as long as your origin data is a string or **nocopy-cast** is safe for your []byte. We also provide API `MarshalString()` for convenient **nocopy-cast** of encoded JSON []byte, which is safe since sonic's output bytes is always duplicated and unique.
|
||||
|
||||
### Accelerate `encoding.TextMarshaler`
|
||||
To ensure data security, sonic.Encoder quotes and escapes string values from `encoding.TextMarshaler` interfaces by default, which may degrade performance much if most of your data is in form of them. We provide `encoder.NoQuoteTextMarshaler` to skip these operations, which means you **MUST** ensure their output string escaped and quoted following [RFC8259](https://datatracker.ietf.org/doc/html/rfc8259).
|
||||
|
||||
|
||||
### Better performance for generic data
|
||||
In **fully-parsed** scenario, `Unmarshal()` performs better than `Get()`+`Node.Interface()`. But if you only have a part of the schema for specific json, you can combine `Get()` and `Unmarshal()` together:
|
||||
```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)
|
||||
```
|
||||
Even if you don't have any schema, use `ast.Node` as the container of generic values instead of `map` or `interface`:
|
||||
```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)
|
||||
```
|
||||
Why? Because `ast.Node` stores its children using `array`:
|
||||
- `Array`'s performance is **much better** than `Map` when Inserting (Deserialize) and Scanning (Serialize) data;
|
||||
- **Hashing** (`map[x]`) is not as efficient as **Indexing** (`array[x]`), which `ast.Node` can conduct on **both array and object**;
|
||||
- Using `Interface()`/`Map()` means Sonic must parse all the underlying values, while `ast.Node` can parse them **on demand**.
|
||||
|
||||
**CAUTION:** `ast.Node` **DOESN'T** ensure concurrent security directly, due to its **lazy-load** design. However, you can call `Node.Load()`/`Node.LoadAll()` to achieve that, which may bring performance reduction while it still works faster than converting to `map` or `interface{}`
