Authenticators now have a similar mechanism to the `router_options` parameter which enables configurable authentication. The authenticators also have a new initialize entry point which is similar to the createInstance entry point of the filters and routers. The value of `authenticator_options` is passed as a parameter to this function. The return vaulue of the `initialize` entry point is passed to the `create` entry point.
# MaxScale by MariaDB Corporation The MariaDB Corporation MaxScale is an intelligent proxy that allows forwarding of database statements to one or more database servers using complex rules, a semantic understanding of the database statements and the roles of the various servers within the backend cluster of databases. MaxScale is designed to provide load balancing and high availability functionality transparently to the applications. In addition it provides a highly scalable and flexible architecture, with plugin components to support different protocols and routing decisions. MaxScale is implemented in C and makes extensive use of the asynchronous I/O capabilities of the Linux operating system. The epoll system is used to provide the event driven framework for the input and output via sockets. The protocols are implemented as external shared object modules which can be loaded at runtime. These modules support a fixed interface, communicating the entries points via a structure consisting of a set of function pointers. This structure is called the "module object". The code that routes the queries to the database servers is also loaded as external shared objects and are referred to as routing modules. An Google Group exists for MaxScale that can be used to discuss ideas, issues and communicate with the MaxScale community.
