# Supported Data Types

VAST Database supports the following Apache Arrow, Trino, and Apache Spark data types:

| VAST Database data type | Arrow data type | Trino data type | Spark data type |
| --- | --- | --- | --- |
| UINT8, UINT16, UINT32, UINT64 | UINT8, UINT16, UINT32, UINT64 | n/a | n/a |
| INT8, INT16, INT32, INT64 | INT8, INT16, INT32, INT64 | TINYINT, SMALLINT, INTEGER, BIGINT | TINYINT, SMALLINT, INTEGER, BIGINT |
| BOOL | BOOL | BOOLEAN | BOOLEAN |
| FLOAT32, FLOAT64 | FLOAT, DOUBLE | REAL, DOUBLE | REAL, DOUBLE |
| STRING | STRING | VARCHAR | STRING |
| BINARY | BINARY | VARBINARY | BINARY |
| DECIMAL128 | DECIMAL128 | DECIMAL | DECIMAL |
| DATE32 | DATE32 | DATE | DATE |
| TIMESTAMP | TIMESTAMP | TIMESTAMP | TIMESTAMP |
| TIMESTAMP WITH TZ | TIMESTAMP | TIMESTAMP WITH TIMEZONE | TIMESTAMP |
| TIME32 | TIME32 | TIME | n/a |
| TIME64 | TIME64 | TIME | n/a |
| MAP | MAP | MAP | MapType |
| ARRAY | LIST | ARRAY | ArrayType |
| ROW | STRUCT | ROW | StructType |
| UUID | UUID | UUID | CHAR(16) |

> [!TIP]
> Tip

> Pay attention to precision settings when dealing with data types that have a configurable precision. For example, a data type of `timestamp` specified in a Parquet file can be seen as `timestamp(3)` in Trino (as a result of a Trino default setting) while processed as `timestamp(6)` in VAST Database.
