What Hacker News says?

  1. I spent a while looking at this today. It's really interesting. It's not based on SQLite at all (except for borrowing the SQLite shell implementation) but it looks very much like SQLite, in particular: - It's designed to work as an embedded library, eliminating the network overhead you usually get when talking to a database - Each database is a single file on disk - It ships as an "amalgamation" build - a single gia…

  3. The pitch is faster, and more space efficient since column stores are far better for analytics than row stores. Some benchmarks that found ~5-10x speedup: https://uwekorn.com/2019/10/19/taking-duckdb-for-a-spin.html Consider someone who analyzes medium-sized volumes of (slowly-changing) data -- OLAP, not OLTP. People who need to do this primarily have 2 alternatives: * columnar database (redshift, snowflake, bigquer…

  5. Cool! This is the first time hearing about DuckDB, exciting as I heavily use SQLite. And these benchmarks are showing it's 6-15 times faster than sql.js (SQLite) [1], along with another small benchmark I found [2]. I usually just slather on indexes in SQLite tho, so indexed queries may not stand up as well; and might not be as fast when it's on storage, as this is comparing in memory performance (I think?), but I'll…

    Here's a neat story about how an Apple M1 Macbook enjoyed 3x the performance compared to an Apple Intel Macbook using a (hassle to compile) Apache Arrow test instantiation. https://uwekorn.com/2021/01/11/apache-arrow-on-the-apple-m1....
