Cquirrel: Continuous Query Processing over Acyclic Relational Schemas
Summary: Cquirrel is a continuous query engine on Flink for relational schemas with acyclic FK graphs. PK–FK joins on select-project-join-agg queries; real-time deltas on updates; improved multi-way joins, scalability, and fault tolerance over prior CQ engines.
