JDBC
Selekt FFM and Xerial run on Java 25; Selekt JNI runs on Java 11. Comparisons between the Selekt backends therefore include JVM-version effects as well as the native-call mechanism.
Batch Insert
Latest JMH batch-insert results across Xerial and both Selekt backends, updated periodically from CI. Lower is better for both metrics.
Text Stream Reads
Latest JMH results for querying and fully consuming 50,000 16-byte UTF-8 text values through JDBC. Lower is better for both metrics.
