Hi All, WSO2 CEP Team is pleased to announce the Alpha release of WSO2 Complex Event Processor 4.1.0.
WSO2 Complex Event Processor (CEP) can be used to identify the most meaningful events within an event cloud, analyzes their impacts, and acts on them in real time. Built to be extremely high performing it offers significant time saving and affordable acquisition. WSO2 CEP Manager is released under the Apache Software License 2.0.
