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.

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. 

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

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)	} }

./build.sh

docker run -d --name flydb-server --network=host -p 8999:8999 bytestorage/flydb:v1.0

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"

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:

PUT performance: 572.265968ms

GET performance: 355.943926ms

PUT performance: 569.610614ms

GET performance: 297.781977ms

If you have a better way to optimize read and write performance, please submit your 'pr'.

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.
