Miscellaneous
This section provides a complete list of the Miscellaneous properties you can configure in the connection string 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. |
| ConnectionLifeTime | The maximum lifetime of a connection in seconds. Once the time has elapsed, the connection object is disposed. |
| ConnectOnOpen | This property specifies whether to connect to the Parquet when the connection is opened. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| PoolIdleTimeout | The allowed idle time for a connection before it is closed. |
| PoolMaxSize | The maximum connections in the pool. |
| PoolMinSize | The minimum number of connections in the pool. |
| PoolWaitTime | The max seconds to wait for an available connection. |
| 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. |
| UseConnectionPooling | This property enables connection pooling. |
| UserDefinedViews | A filepath pointing to the JSON configuration file containing your custom views. |
