## What is LotusDB

LotusDB is the most advanced key-value store written in Go, extremely fast, compatible with LSM tree and B+ tree, and optimization of badger and bbolt.

Key features:

* **Combine the advantages of LSM and B+ tree**

* **Fast read/write performance**

* **Much lower read and space amplification than typical LSM**

## Design Overview

![](https://github.com/lotusdblabs/lotusdb/blob/main/resource/img/design-overview.png)

## Getting Started

```go

package main

import (

	"github.com/lotusdblabs/lotusdb/v2"

)

func main() {

	// specify the options

	options := lotusdb.DefaultOptions

	options.DirPath = "/tmp/lotusdb_basic"

	// open a database

	db, err := lotusdb.Open(options)

	if err != nil {

		panic(err)

	}

	defer func() {

		_ = db.Close()

	}()

	// put a key

	err = db.Put([]byte("name"), []byte("lotusdb"), nil)

	if err != nil {

		panic(err)

	}

	// get a key

	val, err := db.Get([]byte("name"))

	if err != nil {

		panic(err)

	}

	println(string(val))

	// delete a key

	err = db.Delete([]byte("name"), nil)

	if err != nil {

		panic(err)

	}

}

```
