audit, a more ad-hoc kick-off meeting ensured that no major hurdles emerged. A Cure53, Berlin · 03/08/19 1/9 Dr.-Ing. Mario Heiderich, Cure53 Bielefelder com/vitessio/vitess was used as the codebase to be verified. ▪ branch master commit 092479406b27ae61a8fcd146a0e08af2d51a7245 ◦ Furthermore, the minimal reference client https://github.com/vitessio/messages was used provided as a reference of an installation typical for a general Vitess deployment.
