10.2.9. Miscellaneous
Property | Description |
AggregationsSupported | Whether or not to support aggregations in the Cassandra server. Note that in queries to the provider, you must use single quotes to define strings. |
AllowFiltering | When true, slow-performing queries are processed on the server. |
BatchSize | The maximum size of each batch operation to submit. |
CaseSensitivity | Enable case sensitivity to the CQL sending to the server, if set to True, the identifiers in the CQL will be enclosed in double quotation marks. |
ConnectionLifeTime | The maximum lifetime of a connection in seconds. Once the time has elapsed, the connection object is disposed. |
ConnectOnOpen | This property species whether to connect to the Cassandra when the connection is opened. |
ConsistencyLevel | The consistency level determines how many of the replicas of the data you are interacting with need to respond for the query to be considered a success. |
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. |
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. |

Readonly | You can use this property to enforce read-only access to Cassandra from the provider. |
RowScanDepth | The maximum number of rows to scan to look for the columns available in a table. |
RTK | The runtime key used for licensing. |

Timeout | The value in seconds until the timeout error is thrown, canceling the operation. |
UseConnectionPooling | This property enables connection pooling. |
