Some types of exceptions that the producer reports are encountered synchronously during a call to
KafkaProducer::send, but reported asynchronously via the resultingFutureinstead of being thrown directly from the call tosend. One common example of this is when the size of a record exceeds the client-sidemax.message.bytesconfiguration property; when that happens, a failed future is returned immediately fromKafkaProducer::send.This is all fine, but the current behavior does not take into account the guarantees surrounding the transactional producer's
commitTransactionmethod, which are that:The changes in this PR cause producers to fail on
commitTransactionif any prior calls tosendresulted in one of these aynchronously-reported, synchronously-encountered exceptions.An alternative approach could be to throw these exceptions directly to the caller in
send, but that would alter producer behavior for all users instead of just ones using transactional producers; that tradeoff seems less desirable just to fix an issue that only affects transactional producers.Unit tests are added that cover a variety of cases that may lead to previously-missed exceptions and verify that they cause
KafkaProducer::commitTransactionto fail as expected.Committer Checklist (excluded from commit message)
