# gobitcask

This is an implementation of [Bitcask](https://riak.com/assets/bitcask-intro.pdf) (key/value database) in Golang based on [mini-bitcask](https://github.com/rosedblabs/mini-bitcask/tree/main)

## Usage

```go

package main

import (

	"bytes"

	"fmt"

	"github.com/xingyu-long/gobitcask"

)

func main() {

	db, err := gobitcask.Open("/tmp/gobitcask_main")

	if err != nil {

		panic(err)

	}

	key := []byte("test_key")

	value := []byte("test_value")

	err = db.Put(key, value)

	if err != nil {

		panic(err)

	}

	fmt.Printf("1. Run %s: %s\n", "Put", fmt.Sprintf("put key = %s, value = %s into kv", string(key), string(value)))

	ret_val, err := db.Get(key)

	if err != nil {

		panic(err)

	}

	if bytes.Equal(ret_val, value) {

		fmt.Printf("2. Run %s: %s\n", "Get", fmt.Sprintf("value = %s", string(ret_val)))

	} else {

		panic(fmt.Sprintf("Expected value = %s, Actual value = %s\n", string(value), string(ret_val)))

	}

	err = db.Delete(key)

	if err != nil {

		panic(err)

	}

	fmt.Printf("3. Run %s: %s\n", "Delete", fmt.Sprintf("key = %s", string(key)))

	db.Merge()

	fmt.Printf("4. Run %s: %s\n", "Merge", "merge data and create new DBFile")

	db.Close()

	fmt.Printf("5. Run %s: %s\n", "Close", "close DB")

}
