Miscellaneous
This section provides a complete list of the Miscellaneous properties you can configure in the connection settings for this provider.
| Property | Description |
| AggregateFiles | When set to true, the provider will aggregate all the files in URI directory into a single result. With this option enabled, the AggregatedFiles will be exposed which can be used to query the dataset. |
| BatchSize | The maximum size of each batch operation to submit. |
| Charset | Specifies the session character set for encoding and decoding character data transferred to and from the Parquet file. The default value is UTF-8. |
| ClientCulture | This property can be used to specify the format of data (e.g., currency values) that is accepted by the client application. This property can be used when the client application does not support the machine's culture settings. For example, Microsoft Access requires 'en-US'. |
| Compression | Specifies which compression encoding to be used when creating .parquet files using Create Table Statement and Bulk Inserts. |
| Culture | This setting can be used to specify culture settings that determine how the provider interprets certain data types that are passed into the provider. For example, setting Culture='de-DE' will output German formats even on an American machine. |
| DefaultDomain | This property is used for the Oracle Database Gateway for ODBC. |
| DeleteDownloadedFiles | When set to true, the provider will delete parsed .parquet files downloaded from cloud sources. |
| DirectoryRetrievalDepth | Limit the subfolders recursively scanned when IncludeSubdirectories is enabled. |
| EnableDictionary | When set to true, the provider will enable dictionary encoding when creating .parquet files using Create Table Statement and Bulk Inserts. |
| EnableForeignKeyDetection | Whether to detect the foreign keys in ODBC. |
| ExcludeFiles | Comma-separated list of file extensions to exclude from the set of the files modeled as tables. |
| IncludeDropboxTeamResources | Indicates if you want to include Dropbox team files and folders. |
| IncludeDualTable | Set this property to mock the Oracle DUAL table for better compatibility with Oracle database. |
| IncludeFiles | Comma-separated list of file extensions to include into the set of the files modeled as tables. |
| IncludeSubdirectories | Whether to read files from nested folders. In the case of a name collision, table names are prefixed by the underscore-separated folder names. |
| InsertMode | The behavior when using bulk inserts to create Parquet files. |
| LimitKeySize | The maximum length of a primary key column. |
| MapBigintToVarchar | This property controls whether or not the bigint type maps to SQL_VARCHAR instead of SQL_BIGINT. This property is false by default. |
| MapToInt | This property controls whether or not the long type maps to SQL_INTEGER instead of SQL_BIGINT. This property is false by default. |
| MapToLongVarchar | This property controls whether or not a column is returned as SQL_LONGVARCHAR. |
| MapToWVarchar | This property controls whether or not string types map to SQL_WVARCHAR instead of SQL_VARCHAR. This property is set by default. |
| MaximumColumnSize | The maximum column size. |
| MaxRows | Limits the number of rows returned rows when no aggregation or group by is used in the query. This helps avoid performance issues at design time. |
| MetadataDiscoveryURI | Used when aggregating multiple files into one table, this property specifies a specific file to read to determined the aggregated table schema. |
| Other | These hidden properties are used only in specific use cases. |
| PageSize | (Optional) PageSize value. |
| PathSeparator | Determines the character which will be used to replace the file separator. |
| PseudoColumns | This property indicates whether or not to include pseudo columns as columns to the table. |
| Readonly | You can use this property to enforce read-only access to Parquet from the provider. |
| RTK | The runtime key used for licensing. |
| TemporaryLocalFolder | The path, or URI, to the folder that is used to temporarily download parquet file(s). |
| Timeout | The value in seconds until the timeout error is thrown, canceling the operation. |
| UpperCaseIdentifiers | This property reports all identifiers in uppercase. This is the default for Oracle databases and thus allows better integration with Oracle tools such as the Oracle Database Gateway. |
| UserDefinedViews | A filepath pointing to the JSON configuration file containing your custom views. |
