SodiumDB

A blazingly fast 🚀, low overhead ⬇️, in-memory store built in Rust.
A great fit for an easy out-of-the-box caching solution.

Features 📦

• Easy-to-use REST API out-of-the-box, powered by Actix Web
• Authorization out-of-the-box
• Low overhead
• Simple set up with JSON files
• Blazingly Fast (Capable of several thousand req/s on all operations)
• Memory and Thread safety with the Mutex module
• Point-In-Time Snapshot System to heavily optimize I/O
• Document-like System (see the docs for more info)
• Easy vertical scaling with workers

10-20% faster reads!
Thanks to a point-in-time snapshot system, write speeds remain competitive as well:

Introductory Guide 📖

Getting started 🔎

1. To get started, install the Rust Compiler
2. Clone this repository to a desired directory.
   The automatic setup function will do the rest for you. However, keep reading for manual configuration.
3. Within the project directory, create a folder called dbs.
4. Within this folder, create 2 files; settings.json and db.json
5. In db.json, simply type {}. Or, you can input some JSON for the DB to read and start with.
6. In settings.json, follow this example:

{
    "password": "myAmazingPassword",
    "address": "127.0.0.1",
    "port": 8080,
    "workers": 1,
    "snapshot_seconds": 30,
    "entry_limit": 0
}

workers is the amount of handlers that will process your requests; if you do not set it, it will be set to the number of physical cores on your machine.
snapshot_seconds is the time between each snapshot (when data is written to disk) in seconds. Less time between snapshots can reduce performance. Defaults to 30.
entry_limit is the amount of entries in the database the server allows before rejecting create requests. It defaults to 0 (no limit).
7. Navigate to the project directory and run cargo run --release in the command line. (Do not worry about compile time or a somewhat large binary, this is normal)

Authorization 🔒

1. Pick your favorite HTTP Client to get started. This can be something like Postman, requests for Python, fetch in Node.js, or whatever you prefer.
2. In the client set the request header using the following example:

{"Authorization": "myAmazingPassword"}

Interaction with the DB 🗣️

As of now, Sodium has 3 endpoints; /create, /read and /delete, all of which use the POST method.

Create requires a JSON body. Simply add a JSON body to your request and it'll write it to the database.
Read and Delete are very similar. Follow the following example:

{"entry": "entry_to_get_or_delete"}

Read will get the value of the entry if it exists, and Delete will delete it.

Basic Ping Request:

r = requests.get('http://127.0.0.1:8080')
assert r.text == "Hello! This endpoint is here to make sure the SodiumDB REST API is up and running properly :)"

Here is a basic read/write using Python:

requests.post('http://127.0.0.1:8080/create', headers={"Authorization": "myAmazingPassword"}, json={"hello": "world"})
r = requests.post('http://127.0.0.1:8080/read', headers={"Authorization": "myAmazingPassword"}, json={"entry": "hello"})
assert r.json()["result"] == "world"

Note that 4xx errors will always return text responses (i.e "Data Not Found" if a resource could not be found)
Ensure you account for this in your codebase, if needed.
