Development of Harry is currently in progress. Once complete, contributors envision its black-box model and verifier to act as a test to which compute power can be dedicated indefinitely.

Shepherd: Jordan West

Users upgrading from Cassandra 3.0.x to trunk will pick up CASSANDRA-11206 in the process.
