Miscellaneous

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


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.
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 .
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.
ConnectOnOpenSpecifies whether the provider establishes a connection to Cassandra immediately upon opening the connection. Set ConnectOnOpen to True if immediate connectivity verification is necessary.
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.
DefaultDomainThis property is used for the Oracle Database Gateway for ODBC.
EnableForeignKeyDetectionWhether to detect the foreign keys in ODBC.
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.
IncludeDualTableSet this property to mock the Oracle DUAL table for better compatibility with Oracle database.
LimitKeySizeThe maximum length of a primary key column.
MapBigintToVarcharThis property controls whether or not the bigint type maps to SQL_VARCHAR instead of SQL_BIGINT. This property is false by default.
MapToIntThis property controls whether or not the long type maps to SQL_INTEGER instead of SQL_BIGINT. This property is false by default.
MapToLongVarcharThis property controls whether or not a column is returned as SQL_LONGVARCHAR.
MapToWVarcharThis property controls whether or not string types map to SQL_WVARCHAR instead of SQL_VARCHAR. This property is set by default.
MaximumColumnSizeThe maximum column size.
MaxRowsSpecifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
NullToUnsetUse unset instead of NULL in CQL query when performing INSERT operations.
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 Cassandra.
PseudoColumnsSpecifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'.
QueryPassthroughThis option passes the query to the Cassandra server as is.
ReadonlyToggles read-only access to Cassandra from the provider.
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.
TimeoutSpecifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
UpperCaseIdentifiersThis property reports all identifiers in uppercase. This is the default for Oracle databases and thus allows better integration with Oracle tools such as the Oracle Database Gateway.
UseJsonFormatWhether to submit and return the JSON encoding for CQL data types.
UserDefinedViewsSpecifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file.
VarintToStringMap Cassandra VARINT to String value.
