Here’s the difference between Apache Flink and Rill Data. The comparison is based on pricing, deployment, business model, and other important factors.
Apache Flink is an open source project of The Apache Software Foundation (ASF). The Apache Flink project originated from the Stratosphere research project.
Rill makes it easy to create and consume metrics by combining a SQL-based data modeler, real-time database, and metrics dashboard into a single product—a simple alternative to complex BI stacks.
