sqlite-vec/TODO

# partition

- [ ] UPDATE on partition key values
  - remove previous row from chunk, insert into new one?
- [ ] properly sqlite3_vtab_nochange / sqlite3_value_nochange handling


# auxiliary columns

- later:
  - NOT NULL?
  - perf: INSERT stmt should be cached on vec0_vtab
  - perf: LEFT JOIN aux table to rowids query in vec0_cursor for rowid/point stmts, to avoid N lookup queries

# metadata filtering
- text comparisons (long)
- `v in (...)` handling
- [ ] test accessing aux values when rowid is different than 1,2,3 etc.
- [ ] add `xyz_info` shadow table with version etc.
- later
  - null!
  - date/datetime
  - remaining TODO items
  - skip invalid validity entries in knn filter?
  - dictionary encoding?
