This module contains Fluo stress tests. Stress tests are different than integration tests in that they are designed to run on a cluster while integration tests only run on MiniFluo in a local environment. This module produces the jar needed to run a stress test on a cluster. Currently, this module only has one stress test (the Trie test) but other tests could be added to this module in the future.

The newest version!
