What is the role of kafka consumer groupThe functions of kafka consumer groups: 1. Load balancing; 2. Fault tolerance; 3. Flexibility; 4. High availability; 5. Scalability; 6. Sequence guarantee; 7. Data compression; 8. Transaction support. Detailed introduction: 1. Load balancing, the consumer group can distribute the message load balance to each consumer in the group, so that each consumer handles an equal load, thereby making full use of cluster resources and improving the overall processing efficiency; 2 , fault tolerance. Within a consumer group, each consumer independently consumes messages assigned to that consumer group. Wait during the consumption process.
How to create topic in kafkaSteps for kafka to create a topic: 1. Install and configure Kafka; 2. Create a Topic; 3. Verify Topic creation; 4. Configure Topic parameters; 5. Consider using Kafka Manager or Confluent Control Center; 6. Precautions. Detailed introduction: 1. Install and configure Kafka. First, make sure that Kafka has been installed correctly and that it is running. According to the needs and environment, configure the parameters of Kafka, etc.
How to solve the repeated consumption problem in kafkaSolutions to Kafka's repeated consumption problem: 1. Handle consumer failures; 2. Use idempotent processing; 3. Message deduplication technology; 4. Use message unique identifiers; 5. Design idempotent producers; 6. Optimize Kafka configuration and consumer parameters; 7. Monitoring and alarming. Detailed introduction: 1. Handle consumer failures. Kafka consumers may fail or exit abnormally, causing processed messages to be re-consumed; 2. Use idempotent processing. Idempotent processing refers to processing the same message. Multiple processes are performed, the results are the same as one process, and so on.
What are the solutions to kafka message backlog?Solutions to Kafka message backlog: 1. Optimize Kafka configuration; 2. Adjust consumer consumption speed; 3. Increase the number of consumers; 4. Optimize producer sending speed; 5. Enable compression function; 6. Use persistent storage; 7 , monitoring and alarming. Detailed introduction: 1. Optimize Kafka configuration. Kafka's configuration parameters can affect its ability to process messages. Optimizing Kafka's configuration can improve its throughput and reliability, thereby reducing message backlog; 2. Adjust consumer consumption speed, etc. .
What is the role of kafka consumer groupThe functions of kafka consumer group: 1. Load balancing; 2. Fault tolerance; 3. Broadcast mode; 4. Flexibility; 5. Automatic failover and leader election; 6. Dynamic scalability; 7. Sequence guarantee; 8. Data compression; 9. Transaction support. Detailed introduction: 1. Load balancing. Consumer groups are the core mechanism for realizing Kafka load balancing. By organizing consumers into groups, the partitions of the topic can be assigned to multiple consumers in the group, thereby achieving load balancing; 2. Fault tolerance, the design of consumer groups allows for fault tolerance and more.
