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

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)
    }
}
