The fastest operation is the one you don’t have to do. When a database natively supports @arrow.apache.org, ADBC can speed up fetching and ingestion by eliminating costly row/column conversions. How much faster is it in practice? We ran some benchmarks to find out. Link below 👇

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 @arrow.apache.org format. Read the new blog post from @ian.columnar.tech and David Li for examples and perf comparisons vs. JDBC. Link in comments👇
