2. What is MaxScale?
• SkySQL's MaxScale is a sophisticated query routing layer.
• Main benefits include:
– Availability – Allowing automated of routing of database operations to
available servers, avoiding failed servers
– Scaling – Partitions the database load between a number of servers.
– Filtering and logging capabilities
– Authentication layer
– Multiple protocol support
• Open source, being released initially as Alpha.
• Supports MySQL and MariaDB 5.5 and later
– Supports Galera Cluster in addition to MySQL and MariaDB replication
– Supports MHA

3. MaxScale Objectives
● To be highly scalable
● Lightweight with small footprint
● Extendable
● Minimum possible latency
● Highly available
● Provide authentication
● Must be transparent to the application

4. MaxScale Core
● Event driven I/O Processor
● Polling, event driven mechanism that is responsible for
dispatching events to the various modules that make up
MaxScale
● Events in Maxscale = Network requests, such as:
● Handling an incoming connection on a listener socket
● Incoming data for a client connection
● Data arriving on a connection from a backend data server
● A socket error on one of the client or database
connections
● A socket closure
