The DuckDB WASM space is really heating up! I released https://sql-workbench.com a few weeks ago, which can be used to query and visualize Parquet, CSV, JSON and Arrow data. There’s also a accompanying tutorial blog post at https://tobilg.com/using-duckdb-wasm-for-in-browser-data-eng...

HN discussionNice tool! I built https://sql-workbench.com/ which runs completely in-browser via DuckDB WASM, and enables querying of remote CSV, JSON, Parquet and Arrow data sources, as well as uploaded local files. Charts are supported as well, see the accompanying blog post https://tobilg.com/using-duckdb-wasm-for-in-browser-data-eng...

HN discussionI publish a daily updated AWS IAM dataset at https://github.com/tobilg/aws-iam-data as well as historized managed IAM policies at https://github.com/tobilg/aws-iam-managed-policies There's also https://www.awsiamdata.com/ which analyzes the AWS IAM data and also contains a changelog. Maybe this helps some people. You can also query the data from your browser: https://tobilg.com/chat-with-a-duck#heading-explore-aws-i…

HN discussionThe SQL Workbench is built upon DuckDB WASM, Perspective.js and React. It supports the querying remote and local data (Parquet, CSV and JSON), data visualizations and the sharing of multiple queries via URL. There‘s also a tutorial blog post at https://tobilg.com/using-duckdb-wasm-for-in-browser-data-eng... that explains common usage patterns. Happy to answer any questions!

HN discussionThe main use case for me for DuckDB is in Data Lake-related tasks where cloud providers often do not provide great/cost-effective/otherwise limited services. In the case of AWS, repartitioning Parquet files in S3 via Athena CTAS statements in limited to 100 active partitions, which is a bummer to work around. Therefore, I’m using DuckDB with repartitioning queries, because it doesn’t have the 100 partition limit. I…
