- `supports_skipping_indices` (UInt8) — Flag that indicates if table engine supports [skipping indices](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-data_skipping-indexes).
- `supports_ttl` (UInt8) — Flag that indicates if table engine supports [TTL](../../engines/table-engines/mergetree-family/mergetree.md#table_engine-mergetree-ttl).
