Finding the Perfect Rules Engine for Big Data

First, we looked at Drools, but we quickly decided that Drools was much more than was required and also not scalable for high volume data processing environment. Besides that, Drool has it's own repository and management that's not integrated with other system in Big Data ecosystem like Data Governance. Aside from that, many developers are generally not familiar with Drools.

Next, we looked at Easy Rules. Easy Rules seemed a lot easier and much easier interface than Drools. Ordering and support for Forward or Backward chain responsibilities were difficult to implement.
