@a2l007 Thanks for your review! As for higher versions of Kafka, `isolation_level` controls the visibility of transactional records. Using READ_UNCOMMITTED makes all records visible. With READ_COMMITTED , non-transactional and COMMITTED transactional records are visible. In other words, if we disable/ignore this property for higher versions of Kafka, Druid consumer will read all the records including non-transactional records, COMMITTED transactional records and UNCOMMITTED transactional records(transactional messages which have not been successfully committed). Just in case, I add info logs when people set `consumeTransactionally` false which will unset `isolation_level=read_committed`. I also modify the docs to make it clear that Druid doesn't perform offset gap check anymore. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
