Dare-DB

GDare-DB is a project that provides an in-memory database utilizing Redis-inspired hashtables implemented in Go here. It offers a lightweight and efficient solution for storing data in memory and accessing it through simple HTTP operations.

Project Purpose

The primary goal of this project is to offer an in-memory database that leverages hashtables for efficient data storage and retrieval. The Go implementation allows using this database as a component in other Go services or integrating it into applications that require rapid access to in-memory data.

Running the Database

Using Docker

To run the database as a Docker image, ensure you have Docker installed on your system. First, navigate to the root directory of your project and execute the following command to build the Docker image:

docker build -t dare-db .

Once the image is built, you can run the database as a Docker container with the following command (note: a configuration option -e DARE_HOST="0.0.0.0" is explicitly set to enable connections from the host machine to the database running within the Docker container):

docker run -d -p "127.0.0.1:2605:2605" -e DARE_HOST="0.0.0.0" dare-db 

This command will start the database as a Docker container in detached mode, exposing port 2605 of the container to port 2605 on your localhost.

Using TLS Version in Docker

Build special Docker image, which will generate certificates

docker build -t dare-db-tls -f Dockerfile.tls.yml .

Once the image is built, you can run the database as a Docker container with the following command:

docker run -d -p "127.0.0.1:2605:2605" -e DARE_HOST="0.0.0.0" -e DARE_PORT=2605 -e DARE_TLS_ENABLED="True" -e DARE_CERT_PRIVATE="/app/settings/cert_private.pem" -e DARE_CERT_PUBLIC="/app/settings/cert_public.pem" dare-db-tls

Access API over HTTPS on https://localhost:2605

How to Use

The in-memory database provides three simple HTTP endpoints to interact with stored data:

GET /get/{key}

This endpoint retrieves an item from the hashtable using a specific key.

Example usage with cURL:

curl -X GET http://localhost:2605/get/myKey

SET /set

This endpoint inserts a new item into the hashtable. The request body should contain the key and value of the new item.

Example usage with cURL:

curl -X POST -d '{"myKey":"myValue"}' http://localhost:2605/set

DELETE /delete/{key}

This endpoint deletes an item from the hashtable using a specific key.

Example usage with cURL:

curl -X DELETE http://localhost:2605/delete/myKey

Example Usage

Below is a simple example of how to use this database in a Go application:

package main

import (
    "fmt"
    "net/http"
    "bytes"
)

func main() {
    // Example of inserting a new item
    _, err := http.Post("http://localhost:2605/set", "application/json", bytes.NewBuffer([]byte(`{"myKey":"myValue"}`)))
    if err != nil {
        fmt.Println("Error while inserting item:", err)
        return
    }

    // Example of retrieving an item
    resp, err := http.Get("http://localhost:2605/get/myKey")
    if err != nil {
        fmt.Println("Error while retrieving item:", err)
        return
    }
    defer resp.Body.Close()

    // Example of deleting an item
    req, err := http.NewRequest("DELETE", "http://localhost:2605/delete/myKey", nil)
    if err != nil {
        fmt.Println("Error while deleting item:", err)
        return
    }
    _, err = http.DefaultClient.Do(req)
    if err != nil {
        fmt.Println("Error while deleting item:", err)
        return
    }
}

2. Create a new branch for your feature. Use number of a newly created issue and keywords (e.g., 10-implement-feature-ABC)

   git checkout -b 10-implement-feature-ABC

3. Add changes to the branch

   git add .

4. Commit your changes

   git commit -am 'add new feature ABC'

5. Push to the branch

   git push origin 10-implement-feature-ABC

6. Open a pull request based on a new branch
7. Provide a short notice in the pull request according to the following template:
