TigerLabs in Princeton on the 2nd floor, walk up and the door will be open. Same that we were using for the old Future of Data - Princeton events 2016-2019. Parking at the school is free. street parking nearby is free. there are meters on some streets and a few blocks away is a paid parking garage. We are joining forces with our friends Cloudera again on a FLiPN amazing journey into Real-Time Streaming Applications with Apache Flink, Apache NiFi, and Apache Pulsar. Discover how to stream data to and from your data lake or data mart using Apache Pulsar™ and Apache NiFi®. Learn how these cloud-native, scalable open-source projects built for streaming data pipelines work together to enable you to quickly build applications with minimal coding.
- Apache NiFi
- Apache Pulsar
- Apache Flink
- Flink SQL
We will show you how to build apps, so download beforehand to Docker, K8, your Laptop, or the cloud.
