Abstract
System, method, and various embodiments for providing a metadata based memory management system are described herein. An embodiment operates by determining metadata of a table of a database indicating whether data of the table is to be stored in memory or disk storage, wherein the table comprises a plurality of columns and a plurality of rows. A first column of the table is identified. A hierarchy of the metadata for the table including a column value, partition value, and table value is determined, wherein the column value is prioritized over the partition value, and wherein the partition value is prioritized over the table value. The data of the table stored in the column is loaded from the disk storage into the memory based on the hierarchy. A query is processed based on the data loaded into the memory.
