Novel techniques for implementing applications, such as event processors (“EPs”), designed in CQL are provided. Event processors, created as a network of CQL operators, can be implemented in SQL. Implementing an event processor in SQL allows the leveraging of significant industry knowledge and experience in research and development of SQL engines. A user can interact with an EP-generator application to design an event processor in CQL. The EP-generator application can implement the event processor by translating the CQL into SQL statements. Event-processing systems can execute the SQL implementation of the event processor in a first computing environment, such as an SQL database. In this manner, systems described herein can execute event processors defined as a network of CQL operators with high performance and scalability.
