Latest Patents

One of his latest patents is a "Data compression, store, and search system." This invention describes various embodiments for a data compression store and search system. An embodiment operates by receiving a query to search a plurality of documents. It determines that the documents are stored in a compressed format comprising a plurality of shells and snippets. A first snippet that includes the query identifier is identified, and a first shell including a reference to the first snippet is identified. A readable version of a first document is assembled from the first shell, and the assembled readable version is provided in response to the query.

Another significant patent is related to "Data aggregation based on hash map data structures." This invention discloses system, method, and computer program product embodiments for providing data aggregation based on hash map data structures. An embodiment operates by receiving a query specifying an input table and an aggregate function. It generates a first thread-local hash map and a second thread-local hash map for the input table and performs a probing function associated with the first thread-local hash map. The embodiment determines an index cardinality associated with the input table and, in response to the determination that the index cardinality exceeds a threshold, performs a duplicate function associated with the second thread-local hash map. It generates a merged hash map by merging the first thread-local hash map and the second thread-local copy map.
