kafka topic CONSUMER命令操作

 

1查看所有topic

# bin/kafka-topics.sh --list --zookeeper localhost:2181

 

2查看消费者组

# ./bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --list

　　

 

3查看指定topic 下面的数据

# ./bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --from-beginning --topic t_by_mq_product_order

　　

 

4查询topic 信息,使用位置

# ./bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group c_by_product_order_group

demo:

GROUP                    TOPIC                 PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG             CONSUMER-ID                                  HOST            CLIENT-ID
c_by_product_order_group t_by_mq_product_order 1          88627           88627           0               rdkafka-2a40e793-b275-46a4-b9fd-c9c63e7763c7 /39.96.7.154    rdkafka
c_by_product_order_group t_by_mq_product_order 2          146339          146339          0               rdkafka-4744eb0c-9d9c-4a06-b167-acbd46431741 /39.96.7.154    rdkafka
c_by_product_order_group t_by_mq_product_order 0          753993          753993          0               rdkafka-055e84f2-577d-4eab-ace5-c225d888c9f5 /39.96.7.154    rdkafka

 

 

5查看kafka特定topic的详情，使用--topic与--describe参数

./bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic t_by_mq_product_order

　　

demo:

Topic: t_by_mq_product_order	PartitionCount: 3	ReplicationFactor: 1	Configs: 
Topic: t_by_mq_product_order	Partition: 0	Leader: 0	Replicas: 0	Isr: 0
Topic: t_by_mq_product_order	Partition: 1	Leader: 0	Replicas: 0	Isr: 0
Topic: t_by_mq_product_order	Partition: 2	Leader: 0	Replicas: 0	Isr: 0

 

6删除topic清空数据

server.properties 设置 delete.topic.enable=true

./bin/kafka-topics.sh --delete --zookeeper bin/kafka-topics.sh --list --zookeeper localhost:9092 --topic topic_by_products
