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
