Miscellaneous
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| BatchSize | Specifies the maximum number of rows included in each batch operation. Set to 0 to submit the entire batch as a single request. |
| BuiltInColumnMapping | A list of column name mappings for MongoDB's built-in columns. |
| Compression | Specify the compression method. Compression is not enabled when it is None. |
| ConnectionLifeTime | Specifies the maximum lifetime of a connection in seconds. When the specified time elapses, the provider closes the connection. Set to 0 or leave empty for no time limit. |
| 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 . |
| FlattenArrays | By default, nested arrays are returned as strings of JSON. The FlattenArrays property can be used to flatten the elements of nested arrays into columns of their own. Set FlattenArrays to the number of elements you want to return from nested arrays. |
| FlattenObjects | Set FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON. |
| GenerateSchemaFiles | Indicates the user preference as to when schemas should be generated and saved. |
| MaxRows | Specifies the maximum rows returned for queries without aggregation or GROUP BY. |
| NoCursorTimeout | The server normally times out idle cursors after an inactivity period (10 minutes) to prevent excess memory use. Set this option to prevent that. |
| Other | Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties. |
| Pagesize | Specifies the maximum number of results to return from MongoDB, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases. |
| PoolIdleTimeout | Specifies the maximum idle time, in seconds, that a connection can remain in the pool before being closed. |
| PoolMaxSize | Specifies the maximum number of connections allowed in the connection pool. The default value is 100. Set to 0 or a negative value to disable pooling. |
| PoolMinSize | Specifies the minimum number of connections maintained in the connection pool. The default value is 1. |
| PoolWaitTime | Specifies the maximum number of seconds a connection request waits for an available connection in the pool. If the wait exceeds this time, an error is returned. The default is 60 seconds. |
| PseudoColumns | Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property. |
| QueryPassthrough | This option passes the query to MongoDB as-is. |
| 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 | Use this property to target a replica set member or members that are associated with 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. Use this property only in environments where the standard licensing method is unsupported or requires a runtime key. |
| ServiceKind | Specify the kind of service. |
| SlaveOK | This property sets whether the provider is allowed to read from secondary (slave) servers. |
| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout. |
| TypeDetectionScheme | Comma-separated options for how the provider will scan the data to determine the fields and datatypes in each document collection. |
| UpdateScheme | Sets replacing or merging target document with updating fields is performed by executing update statement. |
| UseConnectionPooling | Enables the connection pooling feature, which allows the provider to reuse existing connections instead of creating new ones for each request. |
| UseFindAPI | Execute MongoDB queries using db.collection.find(). |
| UserDefinedViews | Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file. |
| WriteConcern | Requests acknowledgment that the write operation has propagated to the specified number of mongod instances. |
| WriteConcernJournaled | Requires acknowledgment that the mongod instances, as specified in the WriteConcern property, have written to the on-disk journal. |
| WriteConcernTimeout | This option specifies a time limit, in milliseconds, for the write concern. |
| WriteScheme | Sets whether the object type for inserted or updated objects is determined from the existing column metadata or the input value type. |
