## Dqlite by Canonical: Replicated SQLite Powerhouse Dqlite, developed by Canonical, is an embeddable and replicated SQL database engine. It builds upon the strengths of SQLite, extending it with features that enable high availability and automatic failover. **Key Features:** * **Distributed SQLite:** Dqlite takes the familiar SQLite engine and adds a network layer. This allows you to connect multiple instances of your application, forming a cluster that acts as a single, highly-available database. * **Raft Consensus:** Dqlite utilizes the Raft consensus algorithm to ensure data consistency across the cluster. Raft ensures all nodes agree on the order in which transactions are applied, preventing data corruption. * **Automatic Failover:** If a node in the cluster fails, Dqlite automatically elects a new leader node to continue processing requests. This minimizes downtime and keeps your application running smoothly. * **Fast and Efficient:** Dqlite is designed for performance. It boasts asynchronous network and disk I/O, ensuring speedy operations. **Benefits of Dqlite:** * **High Availability:** Dqlite eliminates single points of failure, making your application more resilient to hardware issues. * **Scalability:** You can easily scale your database by adding more nodes to the cluster as your data needs grow. * **Easy to Use:** Dqlite integrates well with existing SQLite applications. The included Go client library simplifies development. * **Lightweight Footprint:** Dqlite keeps its memory usage low, making it suitable for resource-constrained environments. **Use Cases:** * **Edge Computing:** Dqlite excels in edge computing scenarios where data needs to be stored and accessed locally but also replicated for central processing or backup. * **Internet of Things (IoT):** Dqlite's lightweight nature and automatic failover make it ideal for managing data collected from IoT devices. * **Embedded Systems:** Dqlite's small footprint allows seamless integration into resource-limited embedded systems. **Resources:** * **Dqlite Website:** Learn more about Dqlite's features and functionalities on the official website here. * **Dqlite GitHub Repository:** Explore the source code and contribute to the project [here](https://github.com/canonical/dqlite). * **Dqlite Documentation:** Get detailed instructions and tutorials for using Dqlite here.
