Show HN: I built a local data lake for AI powered data engineering and analytics (stream-sock-3f5.notion.site) AI

The post announces “Nile Local,” a fully local AI data IDE and data stack aimed at reducing the setup overhead of big-data engineering. It combines a local data lake/storage layer, Spark compute for interactive query testing, and automated “zero-ETL” ingestion with lineage and versioning. The tool also includes AI-assisted analytics and query writing using embedded or cloud LLMs so users can work and iterate on data locally before deploying to the cloud.
