A database system detects a query targeting a first database object stored in a unified persistence format in a persistence store. In response to detecting the query, the database system determines whether to load the first database object in column-loadable format or page-loadable format into an in-memory store. In response to determining to load the first database object in the column-loadable format, the database system determines if a first bit representation of one or more corresponding primitives in the persistence store is compatible with a second bit representation used for storing the primitives in the in-memory store. The database system performs a native copy operation to copy the primitives from the persistence store to the in-memory store if the bit representations are compatible, where the native copy operation involves copying the primitives on a page-by-page basis without decoding and encoding values of the one or more primitives.
