您如何从 Spring-Apache-Kafka-Streams 中的 Kafka 输入主题中读取数据，并对特定的 output 主题进行不同的分析？

Question

I have referred this. but, this is an old post so i'm looking for a better solution if any.

I have an input topic that contains 'userActivity' data. Now I wish to gather different analytics based on userInterest, userSubscribedGroup, userChoice, etc... produced to distinct output topics from the same Kafka-streams-application.

Could you help me achieve this... ps: This my first time using Kafka-streams so I'm unaware of any other alternatives.

Answer 1

For dynamically choosing which topic to send to at runtime based on each record's key-value pairs. Apache Kafka version 2.0 or later introduced a feature called: Dynamic routing

And this is an example of it: https://kafka-tutorials.confluent.io/dynamic-output-topic/confluent.html
