PyRedis

A simple, in-memory key-value store inspired by Redis, designed for educational purposes. PyRedis supports basic key-value operations, expiration times (TTL), and automatic saving/loading of data from a JSON file.

Features

• Set key-value pairs with optional TTL (time-to-live)
• Get values by key, with automatic expiration handling
• Delete keys
• Auto-save and load data from a JSON file
• Command-line interface for easy interaction

Requirements

• Python 3.x

Installation

To get started with PyRedis, clone the repository and navigate to the project directory:

git clone https://github.com/coderooz/PyRedis.git
cd PyRedis

You can also download the repository as a ZIP file and extract it.

Usage

Running the CLI

To run the PyRedis command-line interface, execute:

python pyredis.py

Commands

The following commands are available in the CLI:

• SET: Set a key-value pair. Optionally, specify a TTL (in seconds).

  SET key value
  SET key1 value1, key2 value2, ..., ttl

• GET: Retrieve the value of a key.

  GET key

• DELETE: Remove a key from the store.

  DELETE key

• SAVE: Save the current data to a JSON file.

  SAVE

• LOAD: Load data from a JSON file.

  LOAD

• ENABLE_AUTOSAVE: Enable automatic saving of data.

  ENABLE_AUTOSAVE

• DISABLE_AUTOSAVE: Disable automatic saving of data.

  DISABLE_AUTOSAVE

• EXIT: Exit the CLI.

  EXIT

Example

Here's an example of using the PyRedis CLI:

pyredis> SET country USA
SET country = USA
pyredis> GET country
GET country = USA
pyredis> DELETE country
DELETE country
pyredis> GET country
GET country = None

Configuration

You can customize the following parameters in the PyRedisCLI class:

• savefile_path: Path to the JSON file for saving/loading data (default is pyredis_dump.json).
• expiration_time: Default TTL for keys in seconds (default is 1 year).
