Abstract
A query server performs method of generating a query result using an aggregation pipeline by identifying, based on a query, a sequence of operations to be applied to documents from an unstructured database, in which a portion of the operations are dependent on other operations in the sequence of operations. The pipeline determines, from the operations, lightweight and heavyweight operations, in which the heavyweight operations generate a materialized result have a substantial impact on processing resources. The pipeline defers the lightweight operations until a materialized result is needed, for performing with a corresponding heavyweight operation, in which the materialized result includes either creation of a new document or movement of substantial data from a document. Lightweight operations are grouped with heavyweight operations such that multiple operations can be collapsed into a single operation that act upon the data together thus avoiding the number of materializations.
