本文介绍了如何将Kafka与Elasticsearch连接?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是Kafka的新手，我使用kafka通过logstash收集网络流量(可以)，并且我想将数据从kafka发送到elasticsearch，但是存在一些问题.
我的问题是如何将Kafka与Elasticsearch连接?
netflow到kafka logstash配置:
I am new in Kafka, I use kafka to collect netflow through logstash(it is ok), and I want to send the data to elasticsearch from kafka, but there are some problems.
My question is how can I connect Kafka with Elasticsearch?
netflow to kafka logstash config:
input{
udp{
host => "120.127.XXX.XX"
port => 5556
codec => netflow
}
}
filter{
}
output {
kafka {
bootstrap_servers => "localhost:9092"
topic_id => "test"
}
stdout{codec=> rubydebug}
}
从kafka到elasticsearch logstash:
kafka to elasticsearch logstash:
input {
kafka { }
}
output {
elasticsearch {
hosts => ["120.127.XXX.XX:9200"]
}
stdout{codec=> rubydebug}
}

先谢谢您！
推荐答案
I would suggest using Kafka Connect and its Elasticsearch sink. I actually presented on exactly this subject last night :) Here are the slides.
You can see a detailed example here.
