Completed upgrade to mysql_cpp_connector 8.0.
"Connector/C++ applications that use X DevAPI or X DevAPI for C require a server from MySQL 8.0 (8.0.11 or higher) or MySQL 5.7 (5.7.12 or higher), with X Plugin enabled. For MySQL 8.0, X Plugin is enabled by default. For MySQL 5.7, it must be enabled explicitly."
Code climate issue has no sense. As already said in the today scrum meeting, for now, we can ignore circleci CI. Good job. We can start performance evaluation tests.
