Contribute to confluentinc/librdkafka development by creating an account on GitHub. Understanding the thread safety of Kafka producers is essential for building robust and efficient Think of a Kafka producer as a high-speed postal service that never sleeps. properties file server. consumer pattern using . message ERR_MSG_SIZE_TOO_LARGE - message is larger than configured max size: messages. For instance, when using NATS with wildcard subscriptions, you may want to retrieve the original subject that the producer sent the message to. NET reactive. Multithreaded Producer-Consumer Example Let’s create a program that consists of two parts – a Producer and a Consumer. Each thread will handle a Kafka consumer that subscribes to partitions independently. The producer is thread safe and sharing a single producer instance across threads will generally be faster than having multiple instances. java:468) Answer Sharing a Kafka producer between threads is crucial for optimal throughput and resource utilization in multi-threaded applications.

Once the message is read, it needs to be handed over to the consumer to proce I am trying to write a client as an producer. Similarly, with Kafka, you may need to access the message headers. Creating new Kafka Producer client instances is an expensive operation and doing so for frequently for every request could lead to performance issues with the application. When dealing with multi - threaded applications, thread safety becomes a crucial concern. apache. I need to produce a lot of messages in Kafka as efficient as possible. 1. This topic describes how Kafka producers are designed to enable load balancing and asynchronous send operations. <init>(KafkaProducer. 2-0. I want to use multiple threads for sending events via Kafka's Consumer Java-API. We’ll have 4 producer threads and use the put () method to block until there’s space available in the queue. buffering.
