Latest Patents

Jianan Lu holds a patent titled "Selection pushdown in column stores using bit manipulation instructions." This patent describes systems and methods for processing queries in column-oriented database systems. The process involves identifying which values of column data are to be accessed for a query. A select bitmap is generated, consisting of k bits, where each bit corresponds to a value of the column. The select bitmap is designed so that each bit representing a value to be accessed has a first value, while bits representing values not to be accessed have a second value. Encoded values are extracted from memory for each value represented in the select bitmap by a bit with the first value. These extracted encoded values are then decoded to generate the decoded query data, which is processed to produce result data.
