This will be interesting to try out. I&#x27;ve used all the major cloud event&#x2F;logging systems (Kinesis, Azure EventHubs, etc) and so far Google PubSub is the best in features and performance.<p>Only downside with Google Pubsub can be latency (which I&#x27;m working on fixing by building a gRPC driver) but Kafka has proven to be too complicated to maintain in-house. If heroku can provide the speed without the ops overhead, it&#x27;ll be some good competition to Google&#x27;s option.<p>Also want to note that Jay Kreps who helped build Kafka at LinkedIn is now behind <a href="http:&#x2F;&#x2F;www.confluent.io&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.confluent.io&#x2F;</a> which is like a better&#x2F;enterprise version of Kafka.
