Description

版本：Version:3.1.1.0。 数据库目前有7个topics，每个topics都只有一个消费组。 2台服务器同时一起消费，实际测试发现。数据都已经插入到库中，但是中间会丢失几条数据。 比如在5s内，连续插入10条数据，但是实际队列里面接收到的只有2、3条数据。这个该怎么排查？

Contributor guide

Research direction
Check consumer group offset management, network latency, and subscription configuration. Verify if all topics are subscribed correctly and if the consumer group commits offsets properly. Inspect TDengine logs for any errors or warnings related to subscription.
