KAFKA

Apache Kafka did enable much more and this KStream service is the result, incorporating everything learned... With Kafka we have neither of the problems. A Kafka producer puts the data into Kafka the instant they are saved in the source database and this Business Rules Service consumes the changed data, applies all rules, adds the rule results to every single record and this validated record is saved in another topic. The only question remaining is how to visualize the data. It can be loaded into a Big Data database or together with the actual data into the relational target database. The volume is still large, 1m rows times 100 rules is 100m rows but at least the results do not need to be evaluated and saved for every single day...
