I've been tasked to replace C++ code to Go and I'm quite new to the Go APIs. I am using gob for encoding hundreds of key/value entries to disk pages but the gob encoding has too much bloat that's not needed.
package main
import (
"bytes"
"encoding/gob"
"fmt"
)
type Entry struct {
Key string
Val string
}
func main() {
var buf bytes.Buffer
enc := gob.NewEncoder(&buf)
e := Entry { "k1", "v1" }
enc.Encode(e)
fmt.Println(buf.Bytes())
}
This produces a lot of bloat that I don't need:
[35 255 129 3 1 1 5 69 110 116 114 121 1 255 130 0 1 2 1 3 75 101 121 1 12 0 1 3 86 97 108 1 12 0 0 0 11 255 130 1 2 107 49 1 2 118 49 0]
I want to serialize each string's len followed by the raw bytes like:
[0 0 0 2 107 49 0 0 0 2 118 49]
I am saving millions of entries so the additional bloat in the encoding increases the file size by roughly x10.
How can I serialize it to the latter without manual coding?
