Latest Patents

Qingchun Jiang's latest patents focus on a novel approach to data storage in in-memory databases. One of his key inventions is the "Combined row and columnar storage for in-memory databases for OLTP and analytics workloads." This innovation allows columns of a table to be stored in either row-major format or column-major format within an in-memory database management system (DBMS). For a given table, one set of columns is stored in column-major format, while another set is stored in row-major format. This method, referred to as dual-major format, enables efficient updates directly to column-major columns without the need for creating an interim row-major form. Users can also submit database definition language (DDL) commands to declare the row-major and column-major columns of a table.
