# partition

- UPDATE on partition key values
  - remove previous row from chunk, insert into new one?
- enforce column types on insert?
- allow null values?
- properly sqlite3_vtab_nochange / sqlite3_value_nochange handling


# auxiliary columns

- DELETE and UPDATE support
- in xBestIndex, ensure there are no constraints on any aux column
- enforce column types, ie STRICT?
- 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
