Abstract:
A system for query execution and planning with pipelining and pump operators is provided. In some implementations, the system performs operations comprising identifying a plurality of operators for executing a query, the plurality of operators including a first operator and a second operator, generating a pump operator when the first operator comprises a table scan operator, and/or generating a query plan for execution of the query, the query plan comprising the pump operator and the second operator. The operations can further include executing the pump operator to at least retrieve a portion of a database table, generate a first data portion based on the portion of the database table, and provide the first data portion for the second operator. Related systems, methods, and articles of manufacture are also described.
