| BuiltInColumnMapping | A comprehensive list detailing the mappings of column names for the built-in fields used in MongoDB. |
| Compression | Specifies the compression method used for network communication between the client and the MongoDB server. |
| DataModel | By default, the provider will not automatically discover the metadata for a child table as its own distinct table. To enable this functionality, set DataModel to Relational . |
| DatetimeFormat | Determines the format of datetime values returned by the Document function. This property only takes effect when StrictMode=true. |

| FlattenObjects | This property specifies whether the attributes of objects are flattened into separate columns. |
| GenerateSchemaFiles | Indicates the user preference as to when schemas should be generated and saved. |
| MaxRows | Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY. |
| NoCursorTimeout | The server typically terminates idle cursors after 30 minutes of inactivity to prevent excessive memory usage. Set this option to true to avoid automatic timeouts and keep your cursors active. |
| Other | Specifies additional hidden properties for specific use cases., to be used only when our Support team advises it, to address specific issues. See Remarks for details. |
| Pagesize | Specifies the maximum number of records per page the provider returns when requesting data from MongoDB. |

| QueryPassthrough | Determines whether queries are sent directly to MongoDB without modification. |
| Readonly | Toggles read-only access to MongoDB from the provider. |
| ReadPreference | Set this to a strategy for reading from a replica set. Accepted values are primary, primaryPreferred, secondary, secondaryPreferred, and nearest. |
| ReadPreferenceTags | This property is used to identify and interact with one or more members of a replica set that are linked to specific tags. |
| RowScanDepth | The maximum number of rows to scan to look for the columns available in a table. |
| RTK | Specifies the runtime key for licensing the provider. If unset or invalid, the provider defaults to the standard licensing method. This property is only required in environments where the standard licensing method is unsupported or requires a runtime key. |
| ServiceKind | Specifies the type of service the provider can interact with. |
| SlaveOK | Determines the provider's capability to read data from secondary (slave) servers. It controls whether the provider can access and retrieve information from these backup systems. |

| TypeDetectionScheme | Specifies the method for detecting metadata discovery. |
| UpdateScheme | Specifies the strategy that can be used when executing an update statement. |
| UseFindAPI | Specifies whether MongoDB queries using the method db.collection.find(), allow retrieval of documents from a specific collection based on defined criteria. |
