Introducing KSQL: Open Source Streaming SQL for Apache Kafka

What does it even mean to query streaming data, and how does this compare to a SQL database? Well, it’s actually quite different to a SQL database. Most databases are used for doing on-demand lookups and modifications to stored data. KSQL doesn’t do lookups (yet), what it does do is continuous transformations— that is, stream processing. For example, imagine that I have a stream of clicks from users and a t ...

These have a long history of implementation using a wide range of messaging technologies. But while Apache Kafka™ is a messaging system of sorts, it’s quite different from typical brokers. It comes with both pros and cons and, like a ...
