# MaxScale by MariaDB Corporation
|

|
[](https://travis-ci.org/mariadb-corporation/MaxScale)
|
|
|
|
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.
