When you say “rebase” what do you mean exactly? Is it the application replaying the transaction including the interactive code, or is it the database writing the same rows/pages that were written last time?

SQLite has an experimental change, "BEGIN CONCURRENT", which uses optimistic locking to allow concurrent non-overlapping writes: https://www.sqlite.org/src/doc/begin-concurrent/doc/begin_co...
So the "rebase" could be the exact same pages (no compute) if none of the writes overlap. If they do, you'd likely need to replay the transaction and make new pages (some compute).
