- Gravitino catalog corresponds to the Doris instance.
-- Supports metadata management of Doris (1.2.x).
-- Supports table index.
+- Supports metadata management of Doris (1.2.x, 3.0.x, 4.0.x).
+- Supports table index (PRIMARY_KEY, UNIQUE_KEY, INVERTED, BITMAP (legacy),
ANN/VECTOR).

Doris doesn't support Gravitino `Fixed` `Timestamp_tz` `IntervalDay`
`IntervalYear` `Union` `UUID` type.
The data types other than those listed above are mapped to Gravitino's
**[Unparsed
Type](./manage-relational-metadata-using-gravitino.md#unparsed-type)** that
represents an unresolvable data type since 0.5.0.
:::note
-Gravitino cannot load Doris `array`, `map` and `struct` type correctly,
because Doris doesn't support these types in JDBC.
+Doris `array`, `map`, and `struct` types are loaded as `ExternalType` with the
full type string preserved (e.g. `array<int(11)>`). They are not resolved into
Gravitino native composite types (`ListType`, `MapType`, `StructType`). The
type identifier in `ExternalType` is always lowercase (e.g. `"json"`, not
`"JSON"`), matching Doris JDBC metadata behavior.

+:::tip Version Compatibility
+- `DateV2` type: Doris 1.2+ (required on 4.0.x where `disable_datev1=true`)
+- `Binary` / `VarBinary` type: Doris 4.0+ (not available on 3.x)
+- `Auto-Increment` column: Doris 2.1+
+- `INVERTED` index: Doris 3.0+
+- `ANN` / `VECTOR` index: Doris 4.0.6+
:::
### Table Column Auto-Increment
-Unsupported for now.
+Auto-increment columns are supported on Doris 2.1+. Gravitino validates the
Doris version at table creation time and rejects auto-increment columns on
older versions.
+
+Doris enforces the following constraints (violations are rejected by the Doris
server):
+
+- The table must use `UNIQUE KEY` or `DUPLICATE KEY` model.
+- The auto-increment column must be `BIGINT NOT NULL` with no `DEFAULT` value.
+- Each table can have at most one auto-increment column.
+
+:::note
+Gravitino currently supports creating `UNIQUE KEY` tables via the `UNIQUE_KEY`
index type. To create a `DUPLICATE KEY` table, omit key indexes from the table
definition — Doris defaults to the DUPLICATE model when no key is specified.

### Table Indexes
-- Supports PRIMARY_KEY
+The Doris catalog supports the following index types. Each index applies to a
single column.
+
+| Gravitino Index Type | Doris DDL
| Doris Version |
+|----------------------|------------------------------------------------------------------------|---------------|
+| `PRIMARY_KEY` | `` INDEX `PRIMARY` (col) `` (in the INDEX clause, no
USING) | 1.2+ |
+| `UNIQUE_KEY` | `UNIQUE KEY(col)` (in the table model section, not
INDEX clause) | 1.2+ |
+| `INVERTED` | `INDEX name (col) USING INVERTED`
| 3.0+ |
+| `BITMAP` | `INDEX name (col)` (bare, no USING clause;
write-only, see note below) | 1.2+ |
+| `VECTOR` | `INDEX name (col) USING ANN`
| 4.0.6+ |
- Please be aware that the index can only apply to a single column.
+:::note
+- `PRIMARY_KEY` stays in the INDEX clause as a bare index (e.g. `` INDEX
`PRIMARY` (`id`) ``), with no USING clause.
+- `UNIQUE_KEY` is emitted as a table model declaration (e.g. `` UNIQUE
KEY(`id`) ``), outside the INDEX clause.
+- `BITMAP` is a write-only legacy type for backward compatibility with Doris
1.2.x. The write path generates a bare `INDEX` (no USING clause), but the read
path maps it back to `INVERTED` because Doris 4.0.6 removed BITMAP from the
grammar. Creating a BITMAP index and reading it back will show `INVERTED`.
