Setup

1. Clone the Rep
2. Start Redis server
   chmod +x initialize_redis.sh && ./initialize_redis.sh
3. build server
   go build -o ./build/rpcServer ./server/handlers/*.go
4. build client
   go build -o ./build/rpcClient ./client/*.go

Usage

Programming interface

1. Set Cache

var ctx = context.Background()
_, err := c.Set(ctx, &pb.CacheSetInput{Key: "hello", Value: []byte("123")})
if err != nil {
	panic(err)
}

2. Get Cache

var ctx = context.Background()
resp, err := c.Get(ctx, &pb.CacheGetInput{Key: "hello"})
if err != nil {
	panic(err)
}
fmt.Println(resp)

3. Set User Cache

_, err = c.SetUser(ctx, &pb.User{
	Name:     "john",
	Class:    "V",
	Rollnum:  22,
	Metadata: []byte("smart student"),
})
if err != nil {
	panic(err)
}

4. Get User Cache

user, err := c.GetUser(ctx, &pb.GetUserInput{
		Name:    "john",
		Class:   "V",
		Rollnum: 22,
})
if err != nil {
	panic(err)
}

fmt.Println(user)

Console

1. Run server

./build/rpcServer

2. Set Cache

./build/rpcClient -set your_key your_value

3. Get Cache

./build/rpcClient -get your_key

4. Set User Cache

./build/rpcClient -set-user john V 22 "smart student"

5. Get User Cache

./build/rpcClient -get-user john V 22
