/** \mainpage SkySQL Gateway
|
|
|
|
The SkySQL Gateway is an intelligent proxy that allows forwarding of
|
|
database statements to one or more database server user complex rules
|
|
and a semantic understanding of the database satements and the roles of
|
|
the various servers within the backend cluster of databases.
|
|
|
|
The Gateway is designed to provided load balancing and high avilability
|
|
functionality transparantly to the applications. In addition it provides
|
|
a highly scalable and flexibile architecture, with plugin components to
|
|
support differnt protocols and routing decissions.
|
|
|
|
The Gateway is implemented in C and makes entensive 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 and runtime. These modules support a fixed interface,
|
|
communicating the entries points via a structure consisting of a set of
|
|
function pointers. This structured is called the "module object".
|
|
|
|
The code that routes the queries to the database servers is also loaed
|
|
as external shared objects and are referred to as routing modules.
