Latest Patents

Leilei Ruan holds a patent titled "Non-partitioned field query optimization in data lakes." This invention involves generating a mapping between values of a non-partitioning field and the containing Parquet files of a data lake. The data lake is organized into partitions and Parquet files, with each partition including a subset of the Parquet files. When a query that includes the non-partitioning field in a filter is received, a subset of the containing Parquet files corresponding to the filter is identified based on the mapping. The query is then rewritten to include filters based on this subset, and the results of executing the rewritten query are transmitted or displayed. This patent showcases Leilei's expertise in optimizing data retrieval processes.
