Show HN: TnL – an exotic ETL nobody asked for (github.com)

A new data pipeline development toolkit named TnL has been introduced, allowing users to effortlessly create production-ready Clojure data pipelines from SQL queries. By utilizing the Tsang SQL parser and the Leng universal database library, TnL automates the transformation of SQL into fully functional Clojure applications, significantly reducing boilerplate code required for ETL processes, data migrations, and cross-database synchronization. This approach enables efficient batch generation of pipelines for multiple databases, making the toolkit a powerful asset for data engineers. The significance of TnL lies in its potential to streamline complex data integration tasks across diverse database systems. With features like full SQL parsing, AST export, and support for common databases such as Cassandra and PostgreSQL, TnL provides a robust framework for managing data workflows. The use of Clojure's immutable data structures and type safety further enhances reliability in production environments, while customizable templates and incremental loading capabilities ensure that users can tailor pipelines to their specific needs. Ultimately, TnL aims to address real-world data integration challenges, fostering greater efficiency and versatility within the AI/ML community.
