Products that do what SwiftLake – Lightweight SQL Engine for Iceberg Tables does

At Arcesium, we needed a way to run SQL-driven CRUD operations, manage slowly-changing dimensions, and handle schema evolution on our cloud data lakes—without the overhead of spinning up distributed clusters or relying on vendor-managed query services. That’s why we built SwiftLake, a lightweight open-source library that brings Apache Iceberg and DuckDB together: - Lightweight & cluster-free: Runs as a single Java service with embedded DuckDB—no distributed infra required. - Full CRUD and SCD1/SCD2 support: Reads, inserts/appends, updates, deletes, and merges with ACID guarantees.…

   DuckDB + React = SQLRooms Framework for Analytics Apps Without Backend▲9

   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…

    Open-Source C++ Apache Iceberg Client with Write Support▲8

    Existing OSS C++ projects like ClickHouse and DuckDB support reading from Iceberg tables. Writing requires Spark, PyIceberg, or managed services. In this PR https://github.com/timeplus-io/proton/pull/928, we are open-sourcing a C++ implementation of Iceberg integration. It's an MVP, focusing on REST catalog and S3 read/write(S3 table support coming soon). You can use Timeplus to continuously read data from MSK and stream writes to S3 in the Iceberg format. No JVM. No Python. Just a low-overhead, high-throughput C++ engine. Docker/K8s are optional. Demo…
