PropertyDescription
AggregationsSupportedWhether or not to support aggregations in the Cassandra server. Note that in queries to the provider, you must use single quotes to define strings.
AllowFilteringWhen true, slow-performing queries are processed on the server.
CaseSensitivityEnable 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.
ConsistencyLevelThe 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.
FlattenArraysBy 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.
FlattenObjectsSet FlattenObjects to true to flatten object properties into columns of their own. Otherwise, objects nested in arrays are returned as strings of JSON.
MaxRowsLimits 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.
NullToUnsetUse unset instead of NULL in CQL query when performing INSERT operations.
