# KVRustDrain

KVRustDrain is a Rust library designed for high-performance, real-time key-value storage with asynchronous draining to a relational database. Inspired by Juspay’s KV Framework (part of the euler-hs Haskell ecosystem), it provides a robust solution for applications needing low-latency data access and eventual consistency, such as ride-hailing services or real-time transaction systems.

## Project Description

KVRustDrain aims to bridge the gap between fast, in-memory key-value storage and persistent relational database storage in Rust. It leverages Redis for immediate data operations and asynchronously syncs data to a PostgreSQL database, ensuring both speed and durability. Built with Rust’s type safety and performance in mind, this library is ideal for developers building scalable backend systems under the Free and Open Source Software (FOSS) ethos.

### Key Features

- Real-Time Key-Value Storage: Uses Redis for low-latency CRUD operations.

- Asynchronous Draining: Syncs data from Redis to PostgreSQL in the background.

- Type-Safe Interface: Leverages Rust’s type system and Diesel for safe database interactions.

- Open Source: Licensed under the GNU Affero General Public License v3.0 (AGPL-3.0), ensuring freedom and transparency.

### Use Cases

- Ride-hailing platforms needing instant ride updates with persistent storage.

- Real-time financial transaction processing.

- Any system requiring high-speed data access with eventual consistency.
