Latest Patents

One of Niu's latest patents is titled "Encoding edges in graph databases." This invention provides a system for processing data by obtaining a group of two or more integer values. The system sets a delta encoding tag for each integer value, representing a delta encoding with respect to at least one other integer value in the group. It then calculates an encoded value from the integer value and encodes the length of this value in a length tag. Finally, the integer value is replaced with an encoded version that includes the delta encoding tag, length tag, and encoded value.

Another significant patent is "Atomic updating of graph database index structures." This invention outlines a system for updating an index structure of a graph database. The system includes a first compressed edge store containing a compact representation of edges in the graph at a specific virtual time, along with a series of updates to these edges. At a later virtual time, the system creates a second compact representation and appends further updates to produce a second compressed edge store. The index structure is then updated by atomically replacing references to the first compressed edge store with the second.
