Introduction

Tarantool’s team has released a new C++ connector, which is based on compile-time MsgPack encoder/decoder. Reaching the limits of C++, this library is really state of the art, eliminating any possible overheads. The project idea aims related to it is: Complete providing support of SQL statements and user authorization.

What was done

Providing SQL statements

• Added support for sql-queries. Implemented methods:

  • Connection::execute() - equivalent of box.execute()
  • Connection::prepare() - equivalent of box.prepare()

• Added tests for the methods above. These methods allow you to send sql-queries to the server using the connector.

Providing user authentication

• Added an overload to the Connector::connect() method, which takes a config structure containing address, port, username and password. If the name and password are specified, the user is authorized.
• Added tests to check and as an example of how to use the function.

Future Connector Improvements

• Port connector to Windows/MacOS (rewrite network engine)
• Add wrappers for DDL
