def returns(returnValues: ReturnValues): DynamoDBQuery[In, A]

Note for update(...) ATM both ReturnValues.UpdatedNew and ReturnValues.UpdatedOld will potentially cause a decode error for the high level API if all the attributes are not updated as this will result in partial data being returned and hence a decode error so should not be use.

If these are required then use the low level API for now.

Adds a KeyConditionExpr to a DynamoDBQuery. Example:

// high level type safe API where "email" and "subject" keys are defined using ProjectionExpression.accessors[Student]
val newQuery = query.whereKey(email.partitionKey === "[email protected]" && subject.sortKey === "maths")

// low level API
val newQuery = query.whereKey($("email").partitionKey === "[email protected]" && $("subject").sortKey === "maths")
