Parquet.Net tries to fit natively into .NET environment and map built-in CLR types to Parquet type system. The following table lists the types supported at the moment. These are the types you can specify in the constructor of SchemaElement<TType>:
| CLR Type | Parquet Type | Parquet Annotation |

| System.Byte (byte) | INT32 | UNIT_8 |
| System.SByte (sbyte) | INT32 | UINT_8 |
| byte[] | BYTE_ARRAY | |
| System.Int16 (short) | INT_32 | INT_16 |
| System.UInt16 (ushort) | INT_32 | UINT_16 |
| System.Int32 (int) | INT32 | |
| System.Boolean (bool) | BOOLEAN | |
| System.String (string) | BYTE_ARRAY | UTF8 |
| System.Single (float) | FLOAT | |
| System.Int64 (long) | INT64 | |
| System.Double (double) | DOUBLE | |
