Latest Patents

Hao Qin holds a patent for a method of determining query plans. This method involves obtaining a current query and generating a first literal and a first signature key from it. The process includes checking if the first signature key matches a second signature key stored in a parser cache. It also involves obtaining a literals data structure that corresponds to the second signature key. This data structure comprises a group of literals, a list of high and low boundary intervals, and a parameterization indicator. The method identifies a parameterized literal in the group of literals and determines if a high and low boundary interval for the second parameterized literal contains the first literal, ultimately executing a stored query plan on the current query.
