FluxDB

An in-memory key-value database inspired by Redis. Supports basic key-value storage, common Redis commands, and sorted sets with score-based ordering. The program is multithreaded and does some simple networking using sockets.

Installation

1. Clone the repo

git clone https://github.com/0xVR/FluxDB.git

2. Build the server and client with your preferred compiler. For example:

cd FluxDB
g++ -o server src/server.cpp
g++ -o client src/client.cpp

Usage

Once the server is running, you can use the provided client to connect to it and send commands. Here are the ones currently supported:

• SET key value: Set the value of a key.
• GET key: Get the value of a key.
• DEL key: Delete a key.
• KEYS pattern: Retrieve all keys matching a pattern.
• ZADD key score member: Add a member with a score to the sorted set.
• ZREM key member: Remove a member from the sorted set.
• ZQUERY key min max: Retrieve members from the sorted set with scores in the specified range.
• PEXPIRE key milliseconds: Sets a timeout on a specified key. After the timeout, the key will be automatically deleted.
• PTTL key: Returns the specified keys remaining time-to-live.

For example:

./client set a 1
