Subject Re: Is it possible to enforce an "unique constraint" through Kafka?
Date Wed, 07 Jan 2015 00:34:06 GMT
Kafka is more of a message queue than a data store. You can use it to store
history of the queue (certainly a powerful use case for disaster recovery),
but it's still not really a data store.

>From the Kafka website (kafka.apache.org):
Apache Kafka is a publish-subscribe messaging [queue] rethought as a
distributed commit log.
