This example shows the difference between calling join() on intermediate Java CompletableFuture objects (which block and thus degrade performance) vs. simply making one call to join() (and thus enhancing greater parallelism). These tests demonstrate why join() shouldn't be used in a stream pipeline on a CompletableFuture that hasn't completed since it may impede parallelism.
