SQLite is a widely used embedded database engine, known for its simplicity and lightweight design. However, the original SQLite project does not accept contributions from third parties and does not use third-party code, which can limit its potential for innovation. This talk is an overview of SQLite architecture and an introduction to libSQL: an open source fork of SQLite.
Piotr Sarna will show how this fork can be used in distributed settings, with automatic backups and the ability to replicate data across multiple nodes. libSQL's modifications also include integration with WebAssembly, which allows users to define custom functions and procedures using Wasm, a compact and portable binary format.
You'll learn the reasons behind this fork of SQLite, and the challenges and trade-offs involved in extending the database with these new features. Piotr also presents plans for future work. This talk will be relevant to database researchers and practitioners interested in leveraging SQLite for applications that require custom functions and/or distributed support.
