Abstract
Disclosed herein are system, method, and computer program product embodiments for providing data aggregation based on hash map data structures. An embodiment operates by receiving a query specifying an input table and an aggregate function. The embodiment then generates a first thread-local hash map and a second thread-local hash map for the input table and performs a probing function associated with the first thread-local hash map. The embodiment then determines, based on the first thread-local hash map, an index cardinality associated with the input table. The embodiment then, in response to the determination that the index cardinality exceeds the threshold, performs a duplicate function associated with the second thread-local hash map and generates a second thread-local copy map. The embodiment then merges the first thread-local hash map and the second thread-local copy map, thereby generating a merged hash map.
