Equivalence Reasoning

behavioral

The patch implements most intent (`OPTIMIZE` variants, `PARTITIONED BY` optional types, struct field colon parsing), but it misses a core parser gate: enabling `STRUCT` type parsing for the Databricks dialect (gold adds Databricks to the `Keyword::STRUCT` dialect match in `parse_data_type`). Without that, Databricks `STRUCT<...>` support is incomplete.

Code Review

correctness: 1/4introduced bug risk: 2/4edge case handling: 2/4maintainability idioms: 3/4

The patch implements most requested Databricks OPTIMIZE and PARTITIONED BY work, but likely misses a critical parser-entry change for Databricks STRUCT type recognition, so it probably does not fully satisfy the intended change.

2 findings
Databricks STRUCT support appears only partial
major

The patch updates struct field parsing to allow `field: type`, but does not show the needed dialect gate update that enables `STRUCT` type parsing for Databricks in the main data-type parser branch. This likely leaves Databricks `STRUCT<...>` unsupported despite tests expecting it.

Unscoped parser API changes increase regression risk
minor

The patch modifies error/token access in `parse_column_def_inner` (`expected_ref`, `peek_token_ref`) while implementing Databricks features. These unrelated changes expand risk and make failures harder to attribute.
