How do you stop a producer in Kafka?

To stop a Producer from streaming data, you can just stop that application. (Kill its process, or just don’t send any more data to a Kafka Broker.) You can gracefully stop a Kafka Consumer from consuming streaming data, though.

Can a Kafka consumer also be a producer?

1 Answer. Absolutely. There is no reason why you should not be able to instantiate a consumer and a producer in the same client.

Do we need to close Kafka producer?

The producer has background, I/O threads for turning records into request bytes and transmitting requests to Kafka cluster. The producer must be closed to not leak resources, i.e., connections, thread pools, buffers.

How does Kafka resolve consumer lag?

3 Answers

1. Monitor how much lag is getting reduced in unit time (per minute, let’s assume) by each consumer.
2. If the rate of lag reduction is still too low, and you’d like to increase it, then add appropriate number of consumers.
3. Make sure all your consumers are in the same consumer group.

How do you stop a consumer in Kafka?

3 Answers. Kafka provides an option to pause() and resume() the consumption from a topic. You can use these methods by implementing a wait in between to revive from the memory issue.

What is the producer-consumer problem in multi threaded programming?

The producer-consumer problem is one of the most frequently encountered problems when we attempt multi threaded programming. While not as challenging as some of the other problems in multi-threaded programming, an incorrect implementation of this problem can create a mess of your application.

What are the three semaphore variables used in the producer-consumer problem?

In the producer-consumer problem, we use three semaphore variables: Semaphore S: This semaphore variable is used to achieve mutual exclusion between processes. By using this variable, either Producer or Consumer will be allowed to use or access the shared buffer at a particular time.

Can there be more than one producer in a food chain?

There can be multiple producer. There will be multiple consumers. Once the production of new items is done the producer(s) will let the consumers know so that the consumer will exit after the last item is consumed and processed.
