To check the consumption status of a topic using Kafka commands, you can use the following command:

1. View consumer group information:

kafka-consumer-groups.sh --bootstrap-server <kafka服务器地址> --group <消费者组名称> --describe

This will display detailed information about consumers in a given consumer group, including the current topic being consumed and the offset of the consumption.

1. Viewing consumer offsets for a specific topic.

kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list <kafka服务器地址> --topic <topic名称> --time -1

This will display the consumer offsets for each partition of the given topic.

1. Review the consumption behavior of consumer groups for a specific topic.

kafka-consumer-groups.sh --bootstrap-server <kafka服务器地址> --group <消费者组名称> --topic <topic名称> --describe

This will display the consumption status of a given consumer group on a specific topic, including the offset and lag for each consumer (difference from the latest message offset).

Please make sure to replace , , and with actual values.
