Since you already went half-way, here are the others. * `enable.auto.commit` -> ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG * `auto.commit.interval.ms` -> ConsumerConfig.AUTO_COMMIT_INTERVAL_MS_CONFIG * `session.timeout.ms` -> ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG https://kafka.apache.org/20/javadoc/?org/apache/kafka/clients/consumer/ConsumerConfig.html ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
