One or more non-transitory computer-readable media storing sequences of instructions, which, when executed by one or more processors, cause:

• storing rows in a table in a database, wherein storing rows in said table comprises storing one or more column-major columns of said rows in column-major format and storing one or more row-major columns of said rows in row-major format;
• wherein storing rows in said table further comprises:
• storing said one or more row-major columns in a row partition comprising row pages;
• storing said one or more column-major columns in one or more column partitions, each column partition of said one or more column partitions comprising column pages, wherein said one or more column-major columns include a particular column-major column;
• executing a database transaction, wherein executing said database transaction comprises updating in said database said particular column-major column in-place to a new value;
• committing said database transaction;
• and
• wherein said updating comprises storing said new value in a column page of said one or more column partitions before committing said database transaction.
