kafka性能测试1.0.0

kafka提供工具kafka-producer-perf-test.sh用以压测,

参数

说明

messages               

生产者发送总的消息数量

message-size

每条消息大小

batch-size

每次批量发送消息的数量

topics

生产者发送的topic

threads

生产者使用几个线程同时发送

broker-list 

安装kafka服务的机器ip:port列表

producer-num-retries

一个消息失败发送重试次数

request-timeout-ms

一个消息请求发送超时时间

 

./kafka-producer-perf-test.sh --topic log.business --num-records 1000000 --record-size 500 --throughput 1000000 --threads 100 --batch-size 4096 --producer-props bootstrap.servers=*****:9092 --sync

 

后来发现,这些参数并不适用,其中message-size,batch-size,threads,sync等参数在1.0.0中不适用,不得已根据脚本提示重新找答案

运行命令:

[udap@10 bin]$ ./kafka-producer-perf-test.sh 
usage: producer-performance [-h] --topic TOPIC --num-records NUM-RECORDS [--payload-delimiter PAYLOAD-DELIMITER] --throughput THROUGHPUT [--producer-props PROP-NAME=PROP-VALUE [PROP-NAME=PROP-VALUE ...]]
                            [--producer.config CONFIG-FILE] [--print-metrics] [--transactional-id TRANSACTIONAL-ID] [--transaction-duration-ms TRANSACTION-DURATION] (--record-size RECORD-SIZE |
                            --payload-file PAYLOAD-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
  --payload-delimiter PAYLOAD-DELIMITER
                         provides delimiter to be used when --payload-file is provided. Defaults to new line. Note that this parameter will be ignored if --payload-file is not provided. (default: \n)
  --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.
  --print-metrics        print out metrics at the end of the test. (default: false)
  --transactional-id TRANSACTIONAL-ID
                         The transactionalId to use if transaction-duration-ms is > 0.  Useful  when testing the performance of concurrent transactions. (default: performance-producer-default-transactional-
                         id)
  --transaction-duration-ms TRANSACTION-DURATION
                         The max age of each transaction. The commitTransaction will be called after this this time has elapsed. Transactions are only enabled if this value is positive. (default: 0)

  either --record-size or --payload-file must be specified but not both.

  --record-size RECORD-SIZE
                         message size in bytes. Note that you must provide exactly one of --record-size or --payload-file.
  --payload-file PAYLOAD-FILE
                         file to read the message payloads from. This works only for UTF-8 encoded  text  files.  Payloads  will  be  read from this file and a payload will be randomly selected when sending
                         messages. Note that you must provide exactly one of --record-size or --payload-file.

 

根据提示得到压测命令如下: 

./kafka-producer-perf-test.sh --topic log.business --throughput 100000 --num-records 1000000 --record-size 200 --producer-props bootstrap.servers=******:9092 ack=0

 

其中参数其实脚本都有解释:

--topic topic名称,

--num-records 总共需要发送的消息数,

--record-size 每个记录的字节数,

--throughput 每秒钟发送的记录数,

--producer-props bootstrap.servers=localhost:9092 发送端的配置信息

这里面比之前版本少了好多参数,提示说明producer-props中有一些配置提供,上官网查看:http://kafka.apache.org/documentation/ 找到目录:Producer Configs 发现其中有一些有用的配置,比如acks,batch.size,ssl等,不过这些配置都有默认值,如果值不一样则可以根据提示设置参数,表格比较长,就不摘抄过来了,根据路径过去看。

by the way

kafka性能与每次写入的record size有关,每条记录的大小会严重影响性能,当我记录字节数设置为200时,单点压测性能接近50W requests per second
