Researchers used Bloom filters to enhance SQLite's performance for analytical queries by 7x-10x. They focused on reducing expensive B-tree probes during join operations by implementing new opcodes that utilized Bloom filters, optimizing query execution without significant memory overhead. These changes were integrated into SQLite version 3.38.0.
