The function that creates a delta is (https://www.sqlite.org/src/artifact/5a262051?ln=966-972) and the function that applies a delta is (https://www.sqlite.org/src/artifact/371e8bf06cfb?ln=460-466). If you replace these two functions with your own bit-level delta implementation, then it should do what you want. -- D. Richard Hipp drh at sqlite.org
