Kafka性能测试工具

简介

Kafka本身自带了性能测试的脚本，可以测试发送端和消费端的速度，分别为：
kafka-producer-perf-test.sh
kafka-consumer-perf-test.sh
这两个脚本可以在kafka的bin目录下找到。

发送端

bin/kafka-producer-perf-test.sh

usage: producer-performance [-h] --topic TOPIC --num-records NUM-RECORDS --record-size RECORD-SIZE --throughput THROUGHPUT [--producer-props PROP-NAME=PROP-VALUE [PROP-NAME=PROP-VALUE ...]] [--producer.config CONFIG-FILE] This tool is used to verify the producer performance. optional arguments: -h, --help             show this help message and exit
  --topic TOPIC          produce messages to this topic
  --num-records NUM-RECORDS number of messages to produce
  --record-size RECORD-SIZE message size in bytes
  --throughput THROUGHPUT throttle maximum message throughput to *approximately* THROUGHPUT messages/sec
  --producer-props PROP-NAME=PROP-VALUE [PROP-NAME=PROP-VALUE ...] kafka producer related configuration properties like bootstrap.servers,client.id etc. These configs take  precedence over those passed via --
                         producer.config.
  --producer.config CONFIG-FILE producer config properties file. 

例子:

bin/kafka-producer-perf-test.sh --topic store --record-size 1000 --throughput 2000 --num-records 10000 --producer-props bootstrap.servers=cdh01:9092  client.id=store_client
