### Before Creating the Bug Report - [x] I found a bug, not just asking a question, which should be created in [GitHub Discussions](https://github.com/apache/rocketmq/discussions). - [x] I have searched the [GitHub Issues](https://github.com/apache/rocketmq/issues) and [GitHub Discussions](https://github.com/apache/rocketmq/discussions) of this repository and believe that this is not a duplicate. - [x] I have confirmed that this bug belongs to the current repository, not other repositories of RocketMQ. ### Runtime platform environment ubuntu 24.04 ### RocketMQ version 5.3.1 ### JDK Version 1.8.0 ### Describe the Bug go pull consumer consume fail when storeType=defaultRocksDB ### Steps to Reproduce 1、set `storeType=defaultRocksDB` in broker.conf 2、consume message with go pull consumer: ```go package main import ( "context" "log" "time" "github.com/apache/rocketmq-client-go/v2" "github.com/apache/rocketmq-client-go/v2/rlog" "github.com/apache/rocketmq-client-go/v2/consumer" "github.com/apache/rocketmq-client-go/v2/primitive" ) const ( nameSrvAddr = "127.0.0.1:8200" topic = "test-topic" consumerGroupName = "testPullGroup" tag = "*" ) var pullConsumer rocketmq.PullConsumer var sleepTime = 1 * time.Second func main() { rlog.SetLogLevel("info") var nameSrv, err = primitive.NewNamesrvAddr(nameSrvAddr) if err != nil { log.Fatalf("NewNamesrvAddr err: %v", err) } pullConsumer, err = rocketmq.NewPullConsumer( consumer.WithGroupName(consumerGroupName), consumer.WithNameServer(nameSrv), consumer.WithMaxReconsumeTimes(2), //consumer.WithPullBatchSize(32), ) if err != nil { log.Fatalf("fail to new pullConsumer: %v", err) } selector := consumer.MessageSelector{ Type: consumer.TAG, Expression: tag, } err = pullConsumer.Subscribe(topic, selector) if err != nil { log.Fatalf("fail to Subscribe: %v", err) } err = pullConsumer.Start() if err != nil { log.Fatalf("fail to Start: %v", err) } for { poll() } } func poll() { cr, err := pullConsumer.Poll(context.TODO(), time.Second*5) if consumer.IsNoNewMsgError(err) { return } if err != nil { log.Printf("[poll error] err=%v", err) time.Sleep(sleepTime) return } log.Println("msgList: ", cr.GetMsgList()) log.Println("messageQueue: ", cr.GetMQ()) log.Println("processQueue: ", cr.GetPQ()) pullConsumer.ACK(context.TODO(), cr, consumer.ConsumeSuccess) } ``` ### What Did You Expect to See? expect consume success ### What Did You See Instead? consume fail with message: consumer request topic: test-topic, offset: 0, minOffset: 0, maxOffset: 1, but access logic queue failed. Correct nextBeginOffset to 0 I found the maxMsgNums is 0 in pull request: ``` request: {"code":11,"language":"GO","version":317,"opaque":976,"flag":0,"remark":"","extFields":{"consumerGroup":"testPullGroup","queueId":"1","maxMsgNums":"0","sysFlag":"6","subscription":"*","expressionType":"TAG","bname":"broker-0","topic":"test-topic","queueOffset":"0","commitOffset":"0","suspendTimeoutMillis":"20000","subVersion":"0"}} response: {"code":19,"extFields":{"suggestWhichBrokerId":"0","groupSysFlag":"0","msgCount4Commercial":"0","TRACE_ON":"true","nextBeginOffset":"0","MSG_REGION":"","maxOffset":"26","minOffset":"0","topicSysFlag":"0"},"flag":1,"language":"JAVA","opaque":976,"remark":"OFFSET_FOUND_NULL","serializeTypeCurrentRPC":"JSON","version":475} ``` ### Additional Context the default pullBatchSize of go pull consumer is 0, but works fine with default consume queue. -- This is an automated message from the Apache Git Service.
