# 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

- in xBestIndex, ensure there are no constraints on any aux column
- DELETE and UPDATE support
- 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
