I have a quick look at Drools and EasyRule, their rules are not for filtering. I think we need the simple rules like RocketMQ filters https://rocketmq.apache.org/docs/filter-by-sql92-example/ for example: $.subject == 'myservice' We can implement our own simple Rule engine to process this rules using Parse Tree (https://en.wikipedia.org/wiki/Parse_tree) and JsonPath SDK Concrete Implementation: 1.
