Miscellaneous

This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.

---

Property	Description
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	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.
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	These hidden properties are used only in specific use cases.
Pagesize	The maximum number of results to return per page from MongoDB.
QueryPassthrough	This option passes the query to MongoDB as-is.
Readonly	You can use this property to enforce 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.
SlaveOK	This property sets whether the provider is allowed to read from secondary (slave) servers.
Timeout	The value in seconds until the timeout error is thrown, canceling the operation.
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.
UseFindAPI	Execute MongoDB queries using db.collection.find().
UserDefinedViews	A filepath pointing to the JSON configuration file containing your custom views.
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.
