Kafka Streams in Production: From Use Case to Monitoring

At New Relic we've been heavy users of Kafka for a while now, so it's not a surprise that we've picked up Kafka Streams quite early too. Our teams have built several services that are working in production environment already, at full scale of New Relic data.

In this talk I would like to share our experience with Kafka Streams. We will first discuss when it's a good idea to use it, what your infrastructure should be prepared for and how your architecture might change. We will then go through most common use cases, like data aggregation and enrichment. Last but not least, we will talk through hardening your service before deploying it on production, what metrics to watch for, what to alert on, and what customer instrumentation is recommended.

As a result of this talk, you should have a clear idea of when you might want to use Kafka Streams at your company and what could you expect from running it in production.
