[GitHub] [rocketmq] 309283175 opened a new issue #2840: 事务消息少量丢失问题

309283175 opened a new issue #2840:
URL: https://github.com/apache/rocketmq/issues/2840


   RocketMQ版本：4.4.0
   executeLocalTransaction 程序日志文件表明已经本地事务返回 LocalTransactionState.COMMIT_MESSAGE
   现象：业务部门反馈数据丢失。
   现状：1.通过业务数据key查询RMQ_SYS_TRANS_HALF_TOPIC主题中可以查到预消息。但是在实际的主题中的确是查不到该消息。
   2.由于数据量大，服务端transaction.log基本5分钟就会压缩一个日志包，10个包最多只能保留不到1小时的日志，丢失的这条消息在预主题中产生的时间为下午13:30左右，下午3点钟左右业务部门反馈数据丢失。日志已经刷没了。

   @309283175 建议升级到4.7.0后的版本，针对事务消息做了很多优化。

   本地事务返回COMMIT，不能保证commit消息送到，要依赖回查机制，请确保checkLocalTransaction回调函数也返回了COMMIT
