| Verbosity | The verbosity level that determines the amount of detail included in the log file. |
| LogModules | Core modules to be included in the log file. |
| MaxLogFileSize | A string specifying the maximum size in bytes for a log file (for example, 10 MB). |
| MaxLogFileCount | A string specifying the maximum file count of log files. |
| Property | Description |
| Location | A path to the directory that contains the schema files defining tables, views, and stored procedures. |
| BrowsableSchemas | This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC. |
| Tables | This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC. |
| Views | Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC. |
| Property | Description |
| AutoCache | Automatically caches the results of SELECT queries into a cache database specified by either CacheLocation or both of CacheConnection and CacheProvider . |
| CacheProvider | The name of the provider to be used to cache data. |
| CacheConnection | The connection string for the cache database. This property is always used in conjunction with CacheProvider . Setting both properties will override the value set for CacheLocation for caching data. |
| CacheLocation | Specifies the path to the cache when caching to a file. |
| CacheTolerance | The tolerance for stale data in the cache specified in seconds when using AutoCache . |
| Offline | Use offline mode to get the data from the cache instead of the live source. |
| CacheMetadata | This property determines whether or not to cache the table metadata to a file store. |
| Property | Description |
| BuiltInColumnMapping | A list of column name mappings for MongoDB's built-in columns. |
| 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 when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses. |
| 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. |
| ServiceKind | Specify the kind of service. |
| 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. |
