## 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
## 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"))
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"))
if err != nil {
panic(err)
}
}
```
