Page generation optimization in a parallelized database system

A computer readable storage medium comprises:

• a first memory section that stores operational instructions that when executed by a first set of loader nodes of pluralities of loader nodes of pluralities of computing devices of a plurality of computing device clusters of a parallelized data input sub-system of a database system, cause the first set of loader nodes to:
• ingest a plurality of datasets, wherein a first dataset of the plurality of datasets includes a first plurality of rows of columnar data, and wherein a second dataset of the plurality of datasets includes a second plurality of rows of columnar data;
• determine a first set of processing core resources of pluralities of processing core resources of the pluralities of loader nodes for ingesting the first dataset, wherein a computing device of the pluralities of computing devices includes a plurality of loader nodes of the pluralities of loader nodes, and wherein a loader node of the plurality of loader nodes includes a plurality of processing core resources of pluralities of processing core resources of the database system;
• determine a second set of processing core resources of the pluralities of processing core resources for ingesting the second dataset;
• direct, via first routing data, the first dataset to the first set of processing core resources, wherein the first set of processing core resources is operable to convert the first dataset into a first set of pages for temporary storage within first memory of the first set of processing core resources;
• and
• direct, via second routing data, the second dataset to the second set of processing core resources, wherein the second set of processing core resources is operable to convert the second dataset into a second set of pages for temporary storage within second memory of the second set of processing core resources.
