The results of this research have been applied to SQLite already and were released in v3.38.0.
tl;dr: Bloom filters were great because: minimal memory overhead, goes well with SQLite’s simple implementation, and worked within existing query engine.
Current min is 4 current target is 5, 14 requires target 6, guess i can start there.The question was about enforced minimums throughout versions, i guess only 14 has that requirement.
So fork it...?
