Properties

var allowedAggregateExpressionType: AllowedAggregateExpressionType?

Specifies whether a query can aggregate a transformed column. This applies to the arguments of both aggregate and window functions. Valid values are:

identityColumns

var identityColumns: List<String>?

The identity column, such as user_id, whose distinct values Clean Rooms counts to enforce minimum aggregation thresholds. Currently, you can specify only one column, and its data type must be string, varchar, or char.

minimumIdentityCount

var minimumIdentityCount: Int?

The minimum number of distinct identities that each query output group must represent. This threshold applies to all output columns in the table. To override this threshold for a specific column, use outputColumnThresholds.

outputColumnThresholds

var outputColumnThresholds: List<OutputColumnThreshold>?

The per-column overrides of minimumIdentityCount. An output column without an override uses minimumIdentityCount.

type

var type: AggregationThresholdType?

The type of aggregation that the threshold enforces. Currently, the only supported value is COUNT_DISTINCT, which counts the distinct values in the identity column.
