Abstract
A method and system for executing a query in parallel is disclosed. A master node may receive a query from a client and develop query plans from that query. The query plans may be forwarded to worker nodes for execution, and each query plan may be accompanied by query metadata. The metadata may be stored in a catalog on the master node.
