FlyDB aims to serve as an alternative to in-memory key-value storage (such as Redis) in some cases, aiming to strike a balance between performance and storage cost. It does this by optimizing resource allocation and using cost-effective storage media. By intelligently managing data, FlyDB ensures efficient operations while minimizing storage costs. It provides a reliable solution for scenarios that require a balance between performance and storage costs.
📚 What is FlyDB ?
FlyDB is a high-performance key-value (KV) storage engine based on the efficient bitcask model. It offers fast and reliable data retrieval and storage capabilities. By leveraging the simplicity and effectiveness of the bitcask model, FlyDB ensures efficient read and write operations, resulting in improved overall performance. It provides a streamlined approach to storing and accessing key-value pairs, making it an excellent choice for scenarios that require fast and responsive data access. FlyDB's focus on speed and simplicity makes it a valuable alternative for applications that prioritize performance while balancing storage costs.
🏁 Fast Start: FlyDB
You can install FlyDB using the Go command line tool:
go get github.com/ByteStorage/FlyDB@v1.1.0
Or clone this project from github:
git clone https://github.com/ByteStorage/FlyDB.git
🖥 How to use FlyDB ?
Used by Golang SDK
Here is a simple example of how to use the Linux version:
See flydb/examples for details.
package main
import (
"fmt"
"github.com/ByteStorage/FlyDB/flydb"
"github.com/ByteStorage/FlyDB/config"
)
func main() {
options := config.DefaultOptions
options.DirPath = "/tmp/flydb"
db, _ := flydb.NewFlyDB(options)
err := db.Put([]byte("name"), []byte("flydb-example"))
if err != nil {
fmt.Println("Put Error => ", err)
}
val, err := db.Get([]byte("name"))
if err != nil {
fmt.Println("Get Error => ", err)
}
fmt.Println("name value => ", string(val))
err := db.Delete([]byte("name"))
if err != nil {
fmt.Println("Delete Error => ", err)
}
}
Used By Shell Command
./build.sh
Used By Docker
docker run -d --name flydb-server --network=host -p 8999:8999 bytestorage/flydb:v1.0
Used By Kubernetes
kubectl apply -f kubernetes/flydb-namespace.yaml
kubectl apply -f kubernetes/flydb-deployment.yaml
kubectl apply -f kubernetes/flydb-service.yaml
kubectl wait --for=condition=ready pod -l app=flydb -n flydb-system
kubectl port-forward svc/flydb-service -n flydb-system 8999:8999
When install flydb server by shell/docker/kubernetes, you can use the flydb-cli to connect the flydb server.
./bin/flydb-client 127.0.0.1:8999"
🚀 Performance test
We did a simple performance test of the V1.0.4 version of FlyDB. This test mainly focused on reading and writing large-scale data, and we selected 500,000 random data for testing.
Through testing, we found that in V1.0.4, with 500,000 data:
BTree Index
PUT performance: 572.265968ms
GET performance: 355.943926ms
<img src="./assets/v1.0.4-btree" alt="v1.0.4-btree" style="width: 33%;" />ARTree Index
PUT performance: 569.610614ms
GET performance: 297.781977ms
<img src="./assets/v1.0.4--art" alt="v1.0.4-art" style="width: 33%;" />If you have a better way to optimize read and write performance, please submit your 'pr'.
📢 Benchmark test
We compared the results of a benchmark test using FlyDB V1.0.4 with other kv databases written in golang on the market and found that the read/write performance test results exceeded most open source kv databases.
