 <span class="sd">The Nexmark suite is a series of queries (streaming pipelines) performed</span>
 <span class="sd">on a simulation of auction events. The launcher orchestrates the generation</span>

 <span class="sd">Model</span>
 <span class="sd">  - Person: Author of an auction or a bid.</span>
 <span class="sd">  - Auction: Item under auction.</span>

 <span class="sd"> - Create Person</span>
 <span class="sd"> - Create Auction</span>
 <span class="sd"> - Create Bid</span>

 <span class="sd">Queries</span>
