We really couldn’t add any information to Sadhana Nandakumar’s excellent walkthrough for capturing and propagating database changes using Red Hat AMQ Streams and Red Hat Fuse. She’s done a terrific job of laying out the steps and guiding users through the process of setting up such a system on Red Hat OpenShift. From Sadhana’s text:
The idea is to enable applications to respond almost immediately whenever there is a data change. We capture the changes as they occur using Debezium and stream it using Red Hat AMQ Streams. We then filter and transform the data using Red Hat Fuse and send it to Elasticsearch, where the data can be further analyzed or used by downstream systems.
