%% @doc Given a data set type and data set publication date, asynchronously
%% publishes the requested data set to the specified S3 bucket and notifies
%% the specified SNS topic once the data is available.
%%
%% Returns a unique request identifier that can be used to correlate requests
%% with notifications from the SNS topic. Data sets will be published in
%% comma-separated values (CSV) format with the file name
%% {data_set_type}_YYYY-MM-DD.csv. If a file with the same name already
%% exists (e.g. if the same data set is requested twice), the original file
%% will be overwritten by the new file. Requires a Role with an attached
%% permissions policy providing Allow permissions for the following actions:
%% s3:PutObject, s3:GetBucketLocation, sns:GetTopicAttributes, sns:Publish,
%% iam:GetRolePolicy.
generate_data_set(Client, Input)
