KhighDB

KhighDB is a high-performance, embedded and disaster tolerant KV storage engine.

🌌 Core Features

• Low latency, both for read and write.
• High throughput, especially when writing an incoming stream of random items.
• Powerful storage ability, handle datasets much larger than RAM w/o degradation.
• Crash friendliness, both in terms of fast recovery and not losing data.
• API supports most protocols of redis.

💠 Engine Architecture

KhighDB implementations Bitcask which is a log-structured hash table for fast key/value data.

Additionally, KhighDB uses adaptive-radix-tree to store the mete data of log entries.

⚡ Support Command

🛫 Embedded Usage

Make sure there is go 1.16 or newer in environment and then install KhighDB.

go get -u github.com/Khighness/khighdb

Create or open a database:

opts := khighdb.DefaultOptions(path)
khighDB, err := khighdb.Open(opts)
...
defer khighDB.Close()
...

Write or read the key-value pair:

err := khighDB.Set([]byte("me"), []byte("Khighness"))
...
val, err := khighDB.Get([]byte("me"))
...

🚀 Quick Start

Firstly, startup a Khigh server:

$ go run ./cmd/server/main.go -dbpath='/tmp' -host='127.0.0.1' -port=3333 -databases=16

Secondly, startup a Khigh client:

$ go run ./cmd/client/main.go -h=127.0.0.1 -p=3333
127.0.0.1:3333>set this KhighDB
$2
OK
127.0.0.1:3333>get this
$7
