Abstract
Disclosed herein are system, method, and computer program product embodiments for database aggregation optimization. An embodiment operates by receiving data from a main memory. Within a cache, a first hash table comprising an aggregate hash of a first portion of the data is generated. A second portion of data is partitioned into one or more of partitions. Within the cache, one or more intermediate hash tables are generated. A first hash table is aggregated based on the one or more intermediate hash tables. At least a portion of the data of the final hash table is provided responsive to a query.
