-- Returns a list of solutions that use the given dataset group. When a
-- dataset group is not specified, all the solutions associated with the
-- account are listed. The response provides the properties for each
-- solution, including the Amazon Resource Name (ARN). For more information
-- on solutions, see
-- <https://docs.aws.amazon.com/personalize/latest/dg/API_CreateSolution.html CreateSolution>.
--
-- This operation returns paginated results.
