AggregateUniqueRequest

public static final class AggregateUniqueRequest.Options
extends Object

Optional parameters.

• COLLECTION_NAME: Name of a collection which is to contain the table specified in 'result_table', otherwise the table will be a top-level table. If the collection does not allow duplicate types and it contains a table of the same type as the given one, then this table creation request will fail.
• EXPRESSION: Optional filter expression to apply to the table.
• SORT_ORDER: String indicating how the returned values should be sorted. Supported values:
  • ASCENDING
  • DESCENDING
  The default value is ASCENDING.
• RESULT_TABLE: The name of the table used to store the results. If present, no results are returned in the response. Has the same naming restrictions as tables.
• RESULT_TABLE_PERSIST: If true then the result table specified in result_table will be persisted as a regular table (it will not be automatically cleared unless a ttl is provided, and the table data can be modified in subsequent operations). If false (the default) then the result table will be a read-only, memory-only temporary table. Supported values:
  • TRUE
  • FALSE
  The default value is FALSE.
• TTL: Sets the TTL of the table specified in 'result_table'. The value must be the desired TTL in minutes.

A set of string constants for the parameter options.
