ksqlDB
ksqlDB is an Event Streaming Database. Basically, you turn Kafka Streams(topics) into Databases. Allowing you to have some level of consistency and fast lookups on real-time data. ksqlDB allows you to perform SQL queries on your Kafka topics. It’s possible todo pull-based or even push-based queries. Kafka is getting closer and closer to be a Database and that’s exciting. To be 100% clear Kafka is not a full-fledge database and I would cherry-pick use cases that fit into the model. There is no one-size-fits-all. So today I want to share a simple POC in a video I made for you guys where we will see push queries in action. So Let’s get started!
