How can this be achieved with the API? If you find this article useful subscribe to our blogs and updates. So the time send() is blocked is determined by: Batches will remain in the queue until one of the following occurs: Compressing data batches using the compression.type property improves throughput and reduces the load on storage, but might not be suitable for low-latency applications where the cost of compression or decompression is prohibitive. This All Kafka metrics that you have collected using special tools need first be saved in Graphite. If you think compression is worthwhile, the best type of compression to use will depend on the messages being sent. rev2023.6.8.43485. $ bin/kafka-console-producer.sh --topic quickstart-events --bootstrap-server kafka:9092. Compression will definitely increase throughput at the cost of uncompressing on consumer side. The total number of young or old garbage collection processes performed by the JVM. From the Header Bar Menu, go to the Dashboard panel. Get MetricFire free for 14 days. Time estimate (in seconds) to drain the partition offset On the side navigation, select Explore under the Data section. Even though storage of inflight messages is common in other queue system, Kafka relies on highly replicated underlying storage like HDFS for guaranteed and durable data storage. And in another terminal window, using this generic consumer, read from the topic: $ bin/kafka-console-consumer.sh --topic metrics --from-beginning --bootstrap-server kafka:9092. There is a performance cost to introducing additional checks to the order of delivery. As the lag response.
