### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version master ### Minimal reproduce step ```java final String topic = "test_transaction_topic_read_compacted"; admin.topics().createNonPartitionedTopic(topic); admin.topicPolicies().setCompactionThreshold(topic, 100 * 1024 * 1024); @Cleanup Consumer<String> consumer = this.pulsarClient.newConsumer(Schema.STRING) .topic(topic) .subscriptionName("sub") .subscriptionType(SubscriptionType.Exclusive) .readCompacted(true) .subscribe(); @Cleanup Producer<String> producer = this.pulsarClient.newProducer(Schema.STRING) .topic(topic) .create(); producer.newMessage().key("K1").value("V1").send(); Transaction txn = pulsarClient.newTransaction() .withTransactionTimeout(1, TimeUnit.MINUTES).build().get(); producer.newMessage(txn).key("K2").value("V2").send(); producer.newMessage(txn).key("K3").value("V3").send(); List<String> messages = new ArrayList<>(); while (true) { Message<String> message = consumer.receive(5, TimeUnit.SECONDS); if (message == null) { break; } messages.add(message.getValue()); } Assert.assertEquals(messages, List.of("V1")); ``` ### What did you expect to see? Test pass, the consumer can't read uncommitted messages from compacted topic ### What did you see instead? Test failed, the consumer read uncommitted messages from compacted topic ### Anything else? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
