Im building a streaming application where I will receive logs of various transactions which need to be processed. Planning to use kafka for this, and Im a newbie to kafka. What are the best practices when choosing a topic for kafka, are they supposed to be static values? Also in my case, each log will have a transaction-id. Can I use the value of transaction-id to generate a new topic when a new unique value of transaction-id is published to kafka?

I am learning the designs of Kafka replication, and producers.
And to my surprise, I somehow get the conclusion that it is impossible for producers to know accurately if the messages are committed by the broker, and the safety of writes are agnostic.
