Kafka 总体调优

5.1 如何提升吞吐量

如何提升吞吐量？

1）提升生产吞吐量

buffer.memory：发送消息的缓冲区大小，默认值是 32m，可以增加到 64m。
batch.size：默认是 16k。如果 batch 设置太小，会导致频繁网络请求，吞吐量下降；如果 batch 太大，会导致一条消息需要等待很久才能被发送出去，增加网络延时。
linger.ms，这个值默认是 0，意思就是消息必须立即被发送。一般设置一个 5-100 毫秒。如果 linger.ms 设置的太小，会导致频繁网络请求，吞吐量下降；如果 linger.ms 太长，会导致一条消息需要等待很久才能被发送出去，增加网络延时。
compression.type：默认是 none，不压缩，但是也可以使用 lz4 压缩，效率还是不错的，压缩之后可以减小数据量，提升吞吐量，但是会加大 producer 端的 CPU 开销。

2）增加分区

**3）消费者提高吞吐量 **

调整 fetch.max.bytes 大小，默认是 50m。
调整 max.poll.records 大小，默认是 500 条。

4）增加下游消费者处理能力

5.2 数据精准一次

**1）生产者角度 **

acks 设置为-1 （acks=-1）。
幂等性（enable.idempotence = true） + 事务。

**2）broker 服务端角度 **

分区副本大于等于 2 （--replication-factor 2）。
ISR 里应答的最小副本数量大于等于 2 （min.insync.replicas = 2）。

3）消费者

事务 + 手动提交 offset （enable.auto.commit = false）。
消费者输出的目的地必须支持事务（MySQL、Kafka）。

5.3 合理设置分区数

创建一个只有 1 个分区的 topic。
测试这个 topic 的 producer 吞吐量和 consumer 吞吐量。
假设他们的值分别是 Tp 和 Tc，单位可以是 MB/s。
然后假设总的目标吞吐量是 Tt，那么分区数 = Tt / min（Tp，Tc）。

例如：producer 吞吐量 = 20m/s；consumer 吞吐量 = 50m/s，期望吞吐量 100m/s；

分区数 = 100 / 20 = 5 分区

分区数一般设置为：3-10 个

分区数不是越多越好，也不是越少越好，需要搭建完集群，进行压测，再灵活调整分区个数。

5.4 单条日志大于 1m

参数名称	描述
message.max.bytes	默认 1m，broker 端接收每个批次消息最大值。
max.request.size	默认 1m，生产者发往 broker 每个请求消息最大值。针对 topic 级别设置消息体的大小。
replica.fetch.max.bytes	默认 1m，副本同步数据，每个批次消息最大值。
fetch.max.bytes	默认 Default: 52428800（50 m）。消费者获取服务器端一批消息最大的字节数。如果服务器端一批次的数据大于该值（50m）仍然可以拉取回来这批数据，因此，这不是一个绝对最大值。一批次的大小受 message.max.bytes （broker config） or max.message.bytes （topic config）影响。

5.5 服务器挂了

在生产环境中，如果某个 Kafka 节点挂掉。

正常处理办法：

先尝试重新启动一下，如果能启动正常，那直接解决。
如果重启不行，考虑增加内存、增加 CPU、网络带宽。
如果将 kafka 整个节点误删除，如果副本数大于等于 2，可以按照服役新节点的方式重新服役一个新节点，并执行负载均衡。

5.6 集群压力测试

1）Kafka 压测

用 Kafka 官方自带的脚本，对 Kafka 进行压测。

生产者压测：kafka-producer-perf-test.sh
消费者压测：kafka-consumer-perf-test.sh

2）Kafka Producer 压力测试

（1）创建一个 test topic，设置为 3 个分区 3 个副本

[atguigu@hadoop102 kafka]$ ./bin/kafka-topics.sh --bootstrap-server hadoop102:9092 --create --replication-factor 3 --partitions 3 --topic test
Created topic test.

（2）在/opt/module/kafka/bin 目录下面有这两个文件。我们来测试一下

[atguigu@hadoop105 kafka]$ ./bin/kafka-producer-perf-test.sh --topic test --record-size 1024 --num-records 1000000 --throughput 10000 --producer-props bootstrap.servers=hadoop102:9092,hadoop103:9092,hadoop104:9092 batch.size=16384 linger.ms=0

参数说明：

record-size 是一条信息有多大，单位是字节，本次测试设置为 1k。
num-records 是总共发送多少条信息，本次测试设置为 100 万条。
throughput 是每秒多少条信息，设成-1，表示不限流，尽可能快的生产数据，可测出生产者最大吞吐量。本次实验设置为每秒钟 1 万条。
producer-props 后面可以配置生产者相关参数，batch.size 配置为 16k。

3）Kafka Consumer 压力测试

（1）修改/opt/module/kafka/config/consumer.properties 文件中的一次拉取条数为 500

max.poll.records=500

（2）消费 100 万条日志进行压测

[atguigu@hadoop105 kafka]$ ./bin/kafka-consumer-perf-test.sh --bootstrap-server hadoop102:9092,hadoop103:9092,hadoop104:9092 --topic test --messages 1000000 --consumer.config config/consumer.properties

参数说明：

--bootstrap-server 指定 Kafka 集群地址
--topic 指定 topic 的名称
--messages 总共要消费的消息个数。本次实验 100 万条。

输出结果：

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
2022-01-20 09:58:26:171, 2022-01-20 09:58:33:321, 977.0166, 136.6457, 1000465, 139925.1748, 415, 6735, 145.0656, 148547.1418

（3）一次拉取条数为 2000

1）修改/opt/module/kafka/config/consumer.properties 文件中的一次拉取条数为 2000

max.poll.records=2000

2）再次执行

[atguigu@hadoop105 kafka]$ ./bin/kafka-consumer-perf-test.sh --bootstrap-server hadoop102:9092,hadoop103:9092,hadoop104:9092 --topic test --messages 1000000 --consumer.config config/consumer.properties

输出结果：

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
2022-01-20 10:18:06:268, 2022-01-20 10:18:12:863, 977.5146, 148.2206, 1000975, 151777.8620, 358, 6237, 156.7283, 160489.8188

（4）调整 fetch.max.bytes 大小为 100m

1）修改/opt/module/kafka/config/consumer.properties 文件中的拉取一批数据大小 100m

fetch.max.bytes=104857600

2）再次执行

[atguigu@hadoop105 kafka]$ ./bin/kafka-consumer-perf-test.sh --bootstrap-server hadoop102:9092,hadoop103:9092,hadoop104:9092 --topic test --messages 1000000 --consumer.config config/consumer.properties

输出结果：

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
