Better Way To Consume Kafka Topics With Confluent Parallel Consumer

Better Way To Consume Kafka Topics With Confluent Parallel Consumer The confluent parallel consumer is an open source apache 2.0 licensed java library that enables you to consume from a kafka topic with a higher degree of parallelism than the number of partitions for the input data (the effective parallelism limit achievable via an apache kafka consumer group). this is desirable in many situations, e.g., when. Library: github confluentinc parallel consumera really useful alternative to plain kafka consumer, let's talk about pain points and how parallel.

Kafka Consumer Configuration And Command Tools Of Kafka Consumer The confluent parallel consumer is an open source apache 2.0 licensed java library that enables you to consume from a kafka topic with more parallelism than the number of partitions. in an apache kafka consumer group, the number of partitions is the parallelism limit. The confluent parallel consumer allows you to parallelize processing at three different levels: key level parallelism: different threads will process messages from a single partition in parallel while maintaining kafka’s key based ordering guarantees. unordered parallelism: different threads will process messages from a single partition in an. Multi threaded message consumption with the apache kafka consumer. multithreading is “the ability of a central processing unit (cpu) (or a single core in a multi core processor) to provide multiple threads of execution concurrently, supported by the operating system.”. in situations where the work can be divided into smaller units, which. Kafka has to wait max.poll.interval.ms to detect that our consumer is not poll ing anymore. when kafka decides to rebalance the group, other consumers are only made aware of this decision on their next poll. we never want rebalance to take even more time, so setting a higher max.poll.interval.ms is not great.

Figure 5. time taken to process a large number of messages with a single parallel consumer vs a single kafka consumer, for different key space sizes. as the number of unique keys in the data set increases, the key ordered parallel consumer performance starts to approach that of the unordered parallel consumer. Kafka consumer group tool. kafka includes the kafka consumer groups command line utility to view and manage consumer groups, which is also provided with confluent platform. find the tool in the bin folder under your installation directory. you can also use the confluent cli to complete some of these tasks.
