DuckDB as the New jq (via) The DuckDB CLI tool can query JSON files directly, making it a surprisingly effective replacement for jq. Paul Gross demonstrates the following query:
select license->>'key' as license, count(*) from 'repos.json' group by 1
repos.json contains an array of {"license": {"key": "apache-2.0"}..} objects. This example query shows counts for each of those licenses. # 21st March 2024, 8:36 pm
Announcing DuckDB 0.10.0. Somewhat buried in this announcement: DuckDB has Fixed-Length Arrays now, along with array_cross_product(a1, a2), array_cosine_similarity(a1, a2) and array_inner_product(a1, a2) functions.
This means you can now use DuckDB to find related content (and other tricks) using vector embeddings!
Also notable: “DuckDB can now attach MySQL, Postgres, and SQLite databases in addition to databases stored in its own format. This allows data to be read into DuckDB and moved between these systems in a convenient manner, as attached databases are fully functional, appear just as regular tables, and can be updated in a safe, transactional manner.” # 13th February 2024, 5:57 pm
