MaxLogFileSizeSpecifies the maximum size of a single log file in bytes. For example, '10 MB'. When the file reaches the limit, the provider creates a new log file with the date and time appended to the name.
MaxLogFileCountSpecifies the maximum number of log files the provider retains. When the limit is reached, the oldest log file is deleted to make space for a new one.

Schema


PropertyDescription
LocationSpecifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
BrowsableSchemasOptional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
TablesOptional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
ViewsOptional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .

Caching


PropertyDescription
AutoCacheSpecifies whether the content of tables targeted by SELECT queries is automatically cached to the specified cache database.
CacheDriverThe driver class of a JDBC driver. The specified driver is used to connect to the target database for all caching operations.
CacheConnectionSpecifies the connection string for the specified cache database.
CacheLocationSpecifies the path to the cache when caching to a file.
CacheToleranceNotes the tolerance, in seconds, for stale data in the specified cache database. Requires AutoCache to be set to True.
OfflineGets the data from the specified cache database instead of live MongoDB data.
CacheMetadataDetermines whether the provider caches table metadata to a file-based cache database.

Miscellaneous


PropertyDescription
BatchSizeSpecifies the maximum number of rows included in each batch submitted during batch operations. To submit the entire batch as a single request, set BatchSize to 0 .
BuiltInColumnMappingA comprehensive list detailing the mappings of column names for the built-in fields used in MongoDB.
CompressionSpecifies the compression method used for network communication between the client and the MongoDB server.
ConnectionLifeTimeSpecifies the maximum lifetime of a connection in seconds. When the specified time elapses, the provider closes the connection.
ConnectOnOpenSpecifies whether the provider establishes a connection to MongoDB immediately upon opening the connection. Set ConnectOnOpen to True if immediate connectivity verification is necessary.
DataModelBy 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 .
DatetimeFormatDetermines the format of datetime values returned by the Document function. This property only takes effect when StrictMode=true.
FlattenArraysThis property specifies whether nested array elements are flattened into individual columns. By default, nested arrays are returned as JSON strings. Set this property to the number of elements to extract from nested arrays.
FlattenObjectsThis property specifies whether the attributes of objects are flattened into separate columns.
GenerateSchemaFilesIndicates the user preference as to when schemas should be generated and saved.
MaxRowsSpecifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
NoCursorTimeoutThe server typically terminates idle cursors after 30 minutes of inactivity to prevent excessive memory usage. Set this option to true to avoid automatic timeouts and keep your cursors active.
OtherSpecifies additional hidden properties for specific use cases., to be used only when our Support team advises it, to address specific issues. See Remarks for details.
PagesizeSpecifies the maximum number of records per page the provider returns when requesting data from MongoDB.
PoolIdleTimeoutSpecifies the maximum idle time, in seconds, that a connection can remain in the pool before being closed. Requires UseConnectionPooling=True.
PoolMaxSizeSpecifies the maximum number of connections allowed in the connection pool.
PoolMinSizeSpecifies the minimum number of connections to be maintained in the connection pool at all times.
PoolWaitTimeSpecifies 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.

ReadonlyToggles read-only access to MongoDB from the provider.
ReadPreferenceSet this to a strategy for reading from a replica set. Accepted values are primary, primaryPreferred, secondary, secondaryPreferred, and nearest.
ReadPreferenceTagsThis property is used to identify and interact with one or more members of a replica set that are linked to specific tags.
RowScanDepthThe maximum number of rows to scan to look for the columns available in a table.
RTKSpecifies the runtime key for licensing the provider. If unset or invalid, the provider defaults to the standard licensing method. This property is only required in environments where the standard licensing method is unsupported or requires a runtime key.
ServiceKindSpecifies the type of service the provider can interact with.
SlaveOKDetermines the provider's capability to read data from secondary (slave) servers. It controls whether the provider can access and retrieve information from these backup systems.
TimeoutSpecifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
TypeDetectionSchemeSpecifies the method for detecting metadata discovery.
UpdateSchemeSpecifies the strategy that can be used when executing an update statement.
UseConnectionPoolingEnables the connection pooling feature, which allows the provider to reuse existing connections instead of creating new ones for each request.
