When the configuration was loaded, the dependencies were resolved at the time the objects were constructed. To remove the need to check whether a dependency exists at object creation time, the dependencies can be resolved by the core as a part of the configuration processing. The circular dependency resolution uses a template function to solve the problem in a generic fashion. This might be slightly overkill but it is a good way to test the waters and see whether the functon would be usable in as a utility function. Only explicit object dependencies are resolved. If a module declares a parameter as a string but uses it like an object name, the dependency is not resolved and can fail. As the dependency resolution uses Tarjan's algorithm, it has a side-effect of creating the correct order of objects to meet their dependencies.
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.
For a detailed overview of what MaxScale can do, read the MaxScale page on the MariaDB website.
An Google Group exists for MaxScale that can be used to discuss ideas, issues and communicate with the MaxScale community.
We're also on the #maria and #maxscale channels on FreeNode.
Please report all feature requests, improvements and bugs in the MariaDB Jira.
