In addition to outputting test results to standard output, the script also provides CSV Reporter, which stores the results as a CSV file for easy use in other analysis tools $KAFKA_HOME/bin/kafka-consumer-perf-test.shThe script is used to test the performance of the Kafka consumer, and the test metrics are the same as the

Refer to the message system, currently the hottest Kafka, the company also intends to use Kafka for the unified collection of business logs, here combined with their own practice to share the specific configuration and use. Kafka version 0.10.0.1 Update record 2016.08.15: Introduction to First draft As a suite of large data for cloud computing,

Kafka cluster configuration is relatively simple. For better understanding, the following three configurations are introduced here. Single Node: A broker Cluster Single Node: cluster of multiple Brokers Multi-node: Multi-broker Cluster 1. Single-node single-broker instance Configuration 1. first, start the zookeeper service Kafka. It provides the script for starting zookeeper (in the

byte copies To reduce the problem of large amounts of small I/O operations, the Kafka protocol is built around a collection of messages. Producer a network request can send a message collection instead of sending only one message at a time. In the server side is the message block in the form of appending messages to the log, consumer in the query is also a query for a large number of linear data blocks. Th

intermediate cache and distribution role. The broker distributes and registers the consumer to the system. The role of broker is similar to caching, that is, caching between active data and offline processing systems. The communication between the client and the server is based on a simple, high-performance TCP protocol unrelated to programming languages. Several Basic concepts:Message sending process: Kafka
