| SeparatorCharacter | Specifies the character or characters used to denote hierarchy in flattened structures, such as Maps and List attributes in DynamoDB. |

| UseConnectionPooling | Enables the connection pooling feature, which allows the provider to reuse existing connections instead of creating new ones for each request. |
| UseConsistentReads | Specifies whether consistent reads should always be used when querying DynamoDB. Consistent reads provide the most up-to-date data, but consume more read capacity. |
| UserDefinedViews | Specifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file. |
| UseSimpleNames | Specifies whether or not simple names should be used for tables and columns. |
