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() {
// Set Options
options := lotusdb.DefaultOptions
options.DirPath = "/tmp/lotusdb_basic"
// Open LotusDB
db, err := lotusdb.Open(options)
if err != nil {
panic(err)
}
defer func() {
_ = db.Close()
}()
// Put Key-Value
key := []byte("KV store engine")
value := []byte("LotusDB")
putOptions := &lotusdb.WriteOptions{
Sync: true,
DisableWal: false,
}
err = db.Put(key, value, putOptions)
if err != nil {
panic(err)
}
// Get Key-Value
value, err = db.Get(key)
if err != nil {
panic(err)
}
println(string(value))
// Delete Key-Value
err = db.Delete(key, putOptions)
if err != nil {
panic(err)
}
// Start Compaction of Value Log
err = db.Compact()
if err != nil {
panic(err)
}
