In both Pulse and QStudio, we bundle a core set of JDBC drivers and optionally download others when a user adds a specific database. We do this deliberately to keep the applications lightweight. We care about every megabyte and don\u2019t want to bloat either our product or our users\u2019 SSDs.<\/p>\n
Database Driver Size<\/span><\/h3>\nNotice:<\/p>\n
\n- DuckDB<\/strong>\u00a0 – An entire database that is smaller than both the Snowflake and the Arrow\/flight SQL driver.<\/li>\n
- H2<\/strong> – Another full database (Java-specific) that is smaller than roughly a third of the drivers we ship.<\/li>\n
- Kdb+ – Supports JDBC<\/strong> and has the fastest industry wide bulk inserts while being one .java file (1900 lines, 60KB)<\/li>\n<\/ul>\n
Obviously, a smaller driver or database isn\u2019t always \u201cbetter\u201d in isolation. But having worked closely with these three in production settings, we can say they are exceptional pieces of engineering. The performance these teams achieve with such compact codebases is a testament to strong engineering discipline and a relentless focus on efficiency end-to-end. Huge congratulations to the teams behind them.<\/p>\n
Scale matters\u00a0 but Efficiency is what makes scale sustainable.<\/strong><\/p>\n
