RQLite

About RQLite

A lightweight, distributed relational database built on SQLite and using the Raft consensus protocol. RQLite provides fault-tolerant, replicated SQLite with an easy-to-use HTTP API, ideal for edge computing and embedded applications.

Key Features

• 1Distributed SQLite database using the Raft consensus algorithm
• 2HTTP and gRPC APIs for cross-language and cross-platform access
• 3Leader election and automatic failover for high availability
• 4Lightweight — no external dependencies beyond Python's sqlite3 module
• 5Read consistency levels: strong, weak, and none for latency tradeoffs

How Python Data Engineers Use RQLite

Python data engineers use rqlite for lightweight, distributed configuration stores and metadata databases in pipeline systems where SQLite simplicity is desired but single-node availability is insufficient. The HTTP API allows Python scripts to perform reads and writes without any database driver installation — useful in containerized microservice architectures.
