本次性能测试在正式环境下单台服务器上Kafka处理MQ消息能力进行压力测试。测试包括对Kafka写入MQ消息和消费MQ消息进行压力测试,根据10w、100w和1000w级别的消息处理结果,评估Kafka的处理性能是否满足项目需求。(该项目期望Kafka能够处理上亿级别的MQ消息)
测试使用Kafka自带的测试脚本,通过命令对Kafka发起写入MQ消息和Kafka消费MQ消息的请求。模拟不同数量级的MQ消息写入和MQ消息消费场景,根据Kafka的处理结果,评估Kafka是否满足处理亿级以上的消息的能力。
测试场景 | MQ消息数 | 每秒写入消息数 | 记录大小(单位:字节) |
Kafka消息写入测试 | 10W | 2000条 | 1000 |
10W | 5000条 | 1000 | |
100W | 5000条 | 1000 |
测试场景 | 消费MQ消息数 |
Kafka消息消费测试 | 10W |
100W | |
1000W |
验证带台服务器上Kafka写入消息和消费消息的能力,根据测试结果评估当前Kafka集群模式是否满足上亿级别的消息处理能力。
在服务器上使用Kafka自带的测试脚本,分别模拟10w、100w和1000w的消息写入请求,查看Kafka处理不同数量级的消息数时的处理能力,包括每秒生成消息数、吞吐量、消息延迟时间。Kafka消息吸入创建的topic命名为test_perf,使用命令发起消费该topic的请求,查看Kafka消费不同数量级别的消息时的处理能力。

3. 写入1000w消息压测结果
执行命令
./kafka-producer-perf-test.sh --topic test_perf --num-records 10000000 --record-size 1000 --throughput 5000 --producer-props bootstrap.servers=localhost:9092

kafka-producer-perf-test.sh 脚本命令的参数解析(以100w写入消息为例):
--topic topic名称,本例为test_perf
--num-records 总共需要发送的消息数,本例为100000
--record-size 每个记录的字节数,本例为1000
--throughput 每秒钟发送的记录数,本例为5000
--producer-props bootstrap.servers=localhost:9092 (发送端的配置信息,本次测试取集群服务器中的一台作为发送端,可在kafka的config目录,以该项目为例:/usr/local/kafka/config;查看server.properties中配置的zookeeper.connect的值,默认端口:9092)
本例中写入100w条MQ消息为例,每秒平均向kafka写入了4.77MB的数据,大概是4999.375条消息/秒,每次写入的平均延迟为88.83毫秒,最大的延迟为2869毫秒。
消费MQ消息 | 消费消息总数 (单位:w) | 共消费数据 (单位:M) | 每秒消费数据 (单位:M) | 每秒消费消息数 | 消费耗时 (单位:s) |
消费MQ消息 | 10 | 95.36 | 137 | 143899.3 | 0.695 |
100 | 953.66 | 177.19 | 185804.5 | 5.38 | |
1000 | 9536.73 | 198.25 | 207878.6 | 48.11 |
1. 消费10w消息压测结果
./kafka-consumer-perf-test.sh --broker-list localhost:9092 --topic test_perf --fetch-size 1048576 --messages 100000 --threads 1
注意:此脚本没有--zookeeper选项,参考链接有错误!
必须要执行写入10w消息之后,才能执行上面的命令,否则运行时,会报下面的错误!

2. 消费100w消息压测结果

输出:

3. 消费1000w消息压测结果
./kafka-consumer-perf-test.sh --broker-list localhost:9092 --topic test_perf --fetch-size 1048576 --messages 10000000 --threads 1
输出:
start.time, end.time, data.consumed.in.MB, MB.sec, data.consumed.in.nMsg, nMsg.sec, rebalance.time.ms, fetch.time.ms, fetch.MB.sec, fetch.nMsg.sec 2018-12-06 06:35:54:143, 2018-12-06 06:38:05:585, 9536.9539, 72.5564, 10000221, 76080.8646, 39, 131403, 72.5779, 76103.4451
kafka-consumer-perf-test.sh 脚本命令的参数为:
--broker-list 指定kafka的链接信息,本例为localhost:9092
--topic 指定topic的名称,本例为test_perf,即4.2.1中写入的消息;
--fetch-size 指定每次fetch的数据的大小,本例为1048576,也就是1M
--messages 总共要消费的消息个数,本例为1000000,100w
以本例中消费100w条MQ消息为例总共消费了954.07M的数据,每秒消费数据大小为49.52M,总共消费了1000421条消息,每秒消费51932.15条消息。
一般写入MQ消息设置5000条/秒时,消息延迟时间小于等于1ms,在可接受范围内,说明消息写入及时。
Kafka消费MQ消息时,1000W待处理消息的处理能力如果在每秒20w条以上,那么处理结果是理想的。
根据Kafka处理10w、100w和1000w级的消息时的处理能力,可以评估出Kafka集群服务,是否有能力处理上亿级别的消息。
本次测试是在单台服务器上进行,基本不需要考虑网络带宽的影响。所以单台服务器的测试结果,对评估集群服务是否满足上线后实际应用的需求,很有参考价值。
