Products that do what Connect DuckDB to any database that has an ADBC driver does
Hi everyone, I'm a PhD student in databases at CMU. Over the past few months, I've been interning at Columnar and building a community extension for DuckDB that lets you query Snowflake, Databricks, BigQuery, PostgreSQL, MySQL, and any other system with an ADBC (Arrow Database Connectivity) driver. The extension supports querying ADBC databases directly through a read_adbc table function. It also supports using ATTACH to connect to an ADBC database and then running SELECT, INSERT, COPY, and CTAS statements as if the database were local to DuckDB. You can install it from DuckDB by running:…

I'm one of the core developers of ADBC (Arrow Database Connectivity). This started as a joke — what would it take to call ADBC from COBOL? Turns out, not much. COBOL's fixed-layout record tables and Arrow's columnar arrays make a lot of the same bets about how to represent typed values in memory. The post walks through the architecture and what surprised us. Repo with runnable GnuCOBOL demos for SQLite, DuckDB, and Snowflake: https://github.com/columnar-tech/adbc-cobol

We’ve built SQLRooms, an open-source framework for creating single-node data analytics apps powered by DuckDB. It lets you build fully client-side, data-centric apps using React and DuckDB running in the browser (via WebAssembly) or in Electron. No server or backend is required — apps can work offline, preserve data privacy, and run queries on large datasets with sub-second performance. Features: - Query large datasets in browser with DuckDB (WASM) - Modular design for building composable data UIs (query editors, dashboards, notebooks, etc.) - Data privacy-preserving AI assistant that can…

Hi HN! I built a Snowflake emulator for local development and testing. Testing Snowflake code locally is frustrating – you need a real account (expensive) or mock everything (tedious). I wanted something that just works with the standard [gosnowflake](https://github.com/snowflakedb/gosnowflake) driver or REST API. snowflake-emulator fixes this by: - Using DuckDB as the storage engine - Auto-translating Snowflake SQL (IFF→IF, NVL→COALESCE, DATEADD, etc.) - Supporting gosnowflake driver protocol – no code changes needed - Providing REST API v2 – use from any language…

Open source library for allowing KDB users to interact with DuckDB. The main motivation was to be able to query open data formats on s3 buckets without having to rely on python/pykx. Great for adhoc research when you want to join new data with existing data stored in KDB.
