Building the future of fast universal data connectivity.
Joined April 2025
ADBC drivers in @java? Yes. The latest release of ADBC adds a JNI layer that lets Java apps load drivers, run queries, and fetch results fast in @ApacheArrow format. Read the new blog post from @lidavidm and @ianmcook for examples and perf comparisons vs. JDBC. Link in comments👇
